Description

POLYPEPTIDE COMPOSITIONS AND USES THEREOF

Cross-Reference to Related Applications

This application claims priority to U.S. Provisional Patent Application no. 63/008,192, filed on April 10, 2020, which is incorporated herein by reference in its entirety.

Field

The technology relates to polypeptide compositions for a variety of uses, including the treatment of diseases or conditions that are susceptible to and/or accompanied by microbial infections, tissue injury or damage, wounds or sores and the treatment of surfaces contaminated by microbes and other pathogens.

Background

The treatment of certain diseases or conditions that are susceptible to and/or accompanied by microbial infections, tissue injury or damage, wounds or sores in or on a subject can sometimes pose challenges due to resistance of the microbes to conventional treatments (e.g., with antibiotics, antiseptics and/or oxidizing biocides). Surfaces contaminated by microbes also can sometimes be resistant to disinfection. What is needed are stable compositions, including compositions that are thermally stable at higher temperatures e.g., under certain sterile conditions, in or on a living body, e.g., a homeothermic animal such as a human, or when inflammation is present, which either, kill, inhibit the growth of, or otherwise eliminate microbes, or which permit treatment/disinfection by overcoming, in whole or in part, resistance to traditional approaches that are used in such situations. Stable compositions are needed, for example, which either: (a) kill, inhibit the growth of, degrade, or otherwise reduce or eliminate microbes that are associated with infections, wounds or sores, or that are associated with certain surfaces such as in industrial, dental or health care settings, or (b) render such microbes susceptible to agents that can kill them and/or inhibit their growth and/or degrade, reduce the number of, and/or eliminate them, e.g., from a surface. Summary

Provided herein in certain aspects are compositions, e.g., polypeptide compositions, that include one or more polypeptides selected from among the polypeptide of SEQ ID NO:1 (referred to herein as “Polypeptide Q”), and polypeptides that include a consecutive sequence of amino acids that is 80% or more, or 90% or more identical to a corresponding consecutive sequence of amino acids of Polypeptide Q. In some embodiments, the sequence of amino acids is 80% or more identical, or 90% or more identical to the sequence of amino acids set forth in SEQ ID NO: 1, and in some embodiments, the polypeptide is a polypeptide of SEQ ID NO. 1. Included among the compositions provided herein are pharmaceutical compositions, e.g., for the treatment of diseases or conditions that are susceptible to and/or accompanied by infections, tissue injury or damage, wounds, sores or burns in or on a subject, compositions for treating, e.g., disinfecting, a surface, e.g., in industrial, dental or health care settings, and compositions for removing a biofilm. Also provided herein are combinations of one or more polypeptides of compositions herein and one or more agents, such as a therapeutically active agent (e.g., a therapeutically active agent that does not include a a polypeptide of a composition provided herein) and/or a surface treatment agent (e.g., a surface treatment agent that does not include a polypeptide of a composition provided herein). In one aspect, a combination provided herein comprises one or more, such as, e.g., two, separate agents (for example a polypeptide provided herein and a separate therapeutically active agent or surface treatment agent) for combined treatment, e.g., treatment of a subject or treatment of a surface. Such agents of a combination are administered or applied as separate substances but for combined use. For example, such separate agents may be administered serially, sequentially or concurrently but as separate agents that are not mixed prior to administration. In some aspects, the agents of a combination may be mixed together and administered as a single composition.

In certain aspects, a polypeptide of a composition or combination provided herein contains a consecutive sequence of amino acids that is 80% or more identical, or 90% or more identical to a corresponding consecutive sequence of amino acids set forth in SEQ ID NO:1 and exhibits an enzyme activity and/or biofilm removal activity.

In some aspects, the compositions and combinations provided herein, for example, pharmaceutical compositions and combinations, can be used to treat a disease or condition in a subject. In some aspects, the disease or condition is one that is susceptible to, associated with and/or accompanied by infections, tissues, such as animal (e.g., human) tissue, and/or tissue (e.g., surface tissue) injury or damage, including, for example, wounds, sores or burns in or on a subject. In some aspects, the disease or condition is accompanied by or associated with tissue, including, for example, epithelial tissue, connective tissue, or tissue membranes (e.g., mucous membranes, cutaneous membranes and serous membranes). Examples of a disease and/or condition associated with mucosa include, but are not limited to, an ulcer in the mucosal lining, such as a peptic ulcer, an infection of the lung mucosa in diseases such as cystic fibrosis or tuberculosis, infection of the gums and/or periodontium, such as in gingivitas, infection of the mouth and/or throat (e.g., strep throat and thrush, vaginitis and associated bacterial infections) or an infection in nasal passages, such as COVID-19. Examples of a disease and/or condition associated with an epithelial tissue membrane, e.g. a cutaneous membrane such as skin, include, but are not limited to, bacterial infections (e.g., cellulitis, impetigo), viral (e.g., herpes virus, human papillomavirus) infections (e.g., shingles, cold sores, and warts, and associated bacterial infections), and fungal infections (e.g., athlete’s foot, ringworm and associated bacterial infections). Examples of tissue (e.g., surface tissue) injury or damage, include, but are not limited to, a wound, burn or a sore. The term “wound,” as used herein, refers to an injury, such as a cut, stab or tear, to an external or internal part of the body. In certain aspects, the wound can become infected, or can be associated with an infection. The term “sore,” as used herein, refers to an infected, inflamed and/or diseased area (e.g., a blister, lesion), generally appearing as a break in the skin or mucous membrane, e.g., the lining of an organ, such as the stomach. The term “ulcer” generally refers to a type of sore that erodes the mucous membrane or skin, generally as the result of a disease or other abnormal condition. The term “burn” generally refers to an injury to a tissue resulting from exposure to heat, friction, radiation, electricity or chemicals. Any of the diseases and conditions treated using compositions (e.g., pharmaceutical compositions) and combinations provided herein can be characterized by or associated with an infection. The term “infection,” as used herein, refers to a disease or condition, or a state associated with a disease or condition, in which one or more pathogenic agents such as bacteria, fungi (e.g., yeasts) or viruses, including, e.g., herpes viruses, human papillomavirus and coronaviruses, become established in or on the body of a subject.

A “subject,” as used herein, can be an animal, such as a human being or a non-human animal. As used herein, “treating,” with reference to treating a subject with a disease or condition, means that the disease or condition, or symptoms associated with the disease or condition, are partially or totally alleviated, or the disease or condition and/or symptoms thereof remain static (do not progress) following treatment. Hence, treatment of a disease or condition encompasses prophylaxis, therapy and/or cure. Prophylaxis refers to prevention of a potential disease and/or a prevention of worsening of symptoms or progression of a disease. As used herein, “treatment” means any manner, e.g., by administration of a composition, e.g., a pharmaceutical composition, or combination provided herein and, optionally, an additional therapeutically active agent and/or surface treatment agent, by which a condition, disorder or disease, or symptoms thereof, are ameliorated.

Thus, in certain aspects, provided herein is a pharmaceutical composition that includes: one or more polypeptides containing the sequence of amino acids set forth in SEQ ID NO:1 (Polypeptide Q) and/or containing a consecutive sequence of amino acids that is 80% or more, or 90% or more identical to a corresponding consecutive sequence of amino acids set forth in SEQ ID NO:1.

The term “microbicidal” refers to the killing of microorganisms or microbes, used interchangeably herein. A microorganism, referred to interchangeably herein as a “microbial cell,” “microbe,” or “microbial organism,” is a microscopic organism that is multicellular or unicellular. Unicellular microorganisms may exist as a single cell or within a colony of cells. Many microorganisms are capable of dividing and proliferating. Microorganisms include prokaryotic microorganisms (e.g., bacteria), non-prokaryotic (e.g., eukaryotic) microorganisms and viruses. Examples of eukaryotic organisms include yeast, filamentous fungi, protists, plants, algae and amoeba. An organism or microorganism can include one or more of the following features: aerobe, anaerobe, filamentous, non-filamentous, monoploid, haploid, diploid, auxotrophic and/or non- auxotrophic, e.g., prototrophic. Some microorganisms are pathogenic and may be associated with and/or capable of causing disease. Pathogenic microorganisms, also referred to as pathogens, include primary pathogens and opportunistic pathogens.

In certain aspects, the microbes are bacteria and the compositions provided herein, such as, for example, pharmaceutical compositions or compositions for treating a surface and/or removing biofilm, provided herein, and combinations provided herein, exhibit “bactericidal” activity, i.e., the ability to kill bacteria. In certain aspects, the microbes are fungi and the compositions provided herein, such as, for example, pharmaceutical compositions or compositions for treating a surface and/or removing biofilm, provided herein, and combinations provided herein, exhibit “fungicidal” activity, i.e., the ability to kill fungi. In certain aspects, the microbes are viruses and the compositions provided herein, such as, for example, pharmaceutical compositions or compositions for treating a surface and/or removing biofilm, provided herein, and combinations provided herein, exhibit “viricidal” activity, i.e., the ability to destroy or inactivate viruses. In aspects, compositions provided herein, such as, for example, pharmaceutical compositions or compositions for treating a surface, provided herein, and combinations provided herein, exhibit biofilm removal activity and, optionally, viricidal activity. In certain aspects, a composition provided herein, such as, for example, a pharmaceutical composition or composition for treating a surface and/or removing biofilm, provided herein, and a combination provided herein, does not exhibit viricidal activity.

The term “microbiostatic” refers to reducing, slowing or stopping the growth of microbes; the microbes eventually die, due to cessation of replication. In certain aspects, the microbes are bacteria and the compositions provided herein, such as, for example, pharmaceutical compositions or compositions for treating a surface and/or removing biofilm, provided herein, and combinations provided herein, exhibit “bacteriostatic” activity, i.e., the ability to reduce, slow or stop the growth of bacteria. In aspects, compositions provided herein, such as, for example, pharmaceutical compositions or compositions for treating a surface, provided herein, and combinations provided herein, exhibit biofilm removal activity and, optionally, one or both of bactericidal activity and bacteriostatic activity. In certain aspects, a composition provided herein, such as, for example, a pharmaceutical composition or composition for treating a surface and/or removing biofilm, provided herein, and a combination provided herein, does not exhibit one or both of bactericidal activity and bacteriostatic activity.

The term “fungistatic” refers to reducing, slowing or stopping the growth of fungi; the microbes eventually die, due to cessation of replication. In certain aspects, the microbes are fungi and the compositions provided herein, such as, for example, pharmaceutical compositions or compositions for treating a surface and/or removing biofilm, provided herein, and combinations provided herein, exhibit “fungistatic” activity, i.e., the ability to reduce, slow or stop the growth of fungi. In aspects, compositions provided herein, such as, for example, pharmaceutical compositions or compositions for treating a surface, provided herein, and combinations provided herein, exhibit biofilm removal activity and, optionally, one or both of fungicidal activity and fungistatic activity. In certain aspects, a composition provided herein, such as, for example, a pharmaceutical composition or composition for treating a surface and/or removing biofilm, provided herein, and a combination provided herein, does not exhibit one or both of fungicidal activity and fungistatic activity.

The term “biofilm” is a term of art that refers to a collective of one or more microorganisms, such as, for example, bacteria and fungi, that accumulate naturally on a variety of surfaces. Non-limiting examples of surfaces can include a surface of an inanimate object, e.g., household and industrial pipes, biomaterials such as contact lenses, medical devices including implants and urinary catheters, as well as a biological surface, e.g., plant and animal tissues. On such surfaces, microorganisms start to form a monolayer and produce an extracellular matrix or “slime” for protection. The matrix contains a variety of components including, but not limited to, extracellular polysaccharides, structural proteins, cell debris and nucleic acids; referred to as extracellular polymeric substances (EPS).

The close proximity of microorganisms to each other enables substrate exchange, the distribution of metabolic products and removal of toxic end products so that the different species can support each other. In addition, the structure of the biofilm communities can protect the microbes within them from attack by antimicrobials (e.g., antibiotics, when the microbes are bacteria), shear forces and the immune system. For example, when a disease or condition in a subject is characterized by or associated with a chronic wound, the formation of a biofilm, e.g., a bacterial biofilm, at the wound often can contribute to inability of the wound to heal by a variety of mechanisms including, but not limited to, the extracellular polysaccharide matrix acting as a physical barrier to host inflammatory cells, the inhibition of complement activation and other host defensive mechanisms leading to an ineffective inflammatory/immune response, the blockade and inactivation of antibiotics and other therapeutically active agents (such as antimicrobial agents), and antiseptic or disinfectant agents, and wound healing inhibition through direct inhibition of keratinocyte migration.

In certain aspects, the compositions provided herein, such as, for example, pharmaceutical compositions or compositions for treating a surface and/or removing biofilm provided herein, and combinations provided herein, contain polypeptide(s) that exhibit biofilm removal activity. “Biofilm removal activity,” as used herein, refers to activity that reduces, and can effect removal of, a biofilm or portion thereof. Removal can be, for example, disruption, degradation, breakdown and/or destruction of biofilm that results in a reduction, e.g., in amount, of a biofilm (e.g., of an intact biofilm) and/or one or more components (e.g., extracellular matrix material, such as EPS, and/or cells, e.g., microbial cells, such as viable microbial cells) thereof. The reduction can be a partial reduction or complete reduction (e.g., elimination). Methods for quantitatively and qualitatively assessing the amount or extent of a biofilm are known in the art and/or described herein. In aspects, the polypeptide(s) exhibit biofilm removal activity and the polypeptide(s) is/are in an amount sufficient to remove at least 20% of the biofilm (or reduce the amount of biofilm by at least 20% as can be evaluated using known methods) associated with a particular area, for example, an area of a surface, a tissue (such as animal (e.g., human) tissue), e.g., mucosa, a site of tissue (e.g., surface tissue) injury or damage, a site of infection, a wound, a sore or a burn in or on a subject. In some aspects, the compositions provided herein, such as pharmaceutical compositions or compositions for treating a surface and/or removing biofilm provided herein, and combinations provided herein, the polypeptide(s), or both the composition (or combination) and the polypeptide(s) do not exhibit microbicidal activity and/or do not exhibit bactericidal activity.

The compositions provided herein, such as pharmaceutical compositions or compositions for treating a surface and/or removing biofilm provided herein, and combinations provided herein, can contain, in certain aspects, a single polypeptide, or can contain, in aspects, a plurality of polypeptides. In certain aspects, the compositions provided herein, such as pharmaceutical compositions or compositions for treating a surface and/or removing biofilm provided herein, and combinations provided herein, consist essentially of a single polypeptide. The phrase “consist(s) essentially of,” as used herein, means that components other than the recited components, if present, do not materially alter the activity of the recited components. Thus, for example, in the context of the compositions, e.g., pharmaceutical compositions or compositions for treating a surface and/or removing biofilm, provided herein, the compositions may include one or more components other than a single polypeptide having the aforementioned sequence characteristics and properties. In some aspects, the compositions, e.g., pharmaceutical compositions or compositions for treating a surface and/or removing biofilm, provided herein consist of a single polypeptide.

In certain aspects, at least one polypeptide in the compositions provided herein, such as pharmaceutical compositions or compositions for treating a surface and/or removing biofilm provided herein, and combinations provided herein, exhibits biofilm removal activity and in certain aspects, the compositions provided herein, such as pharmaceutical compositions or compositions for treating a surface and/or removing biofilm provided herein, and combinations provided herein, contain only one polypeptide exhibiting biofilm removal activity. In some aspects, the polypeptide exhibiting biofilm removal activity contains the sequence of amino acids set forth in SEQ ID NO:1 (Polypeptide Q). In some aspects, the polypeptide exhibiting biofilm removal activity consists essentially of the sequence of amino acids set forth in SEQ ID NO:1 (Polypeptide Q) and in some aspects, the polypeptide exhibiting biofilm removal activity consists of the sequence of amino acid set forth in SEQ ID NO:1 (Polypeptide Q).

In certain aspects, the compositions provided herein, such as pharmaceutical compositions or compositions for treating a surface and/or removing biofilm provided herein, and combinations provided herein, that include at least one polypeptide having biofilm removal activity can be used to remove or reduce the amount of biofilm associated with an area of a surface, a tissue (such as animal (e.g., human) tissue), e.g., mucosa, a site of tissue (e.g., surface tissue) injury or damage, a site of infection, a wound, a sore or a burn in or on a subject. In some aspects, the biofilm is associated with the gums (i.e. , gingiva) and/or periodontium, and in some aspects, the subject having biofilm associated with the gums and/or periodontium has gingivitis and/or periodontal disease. In some aspects, the biofilm is associated with a tooth and, in some aspects, the subject having biofilm associated with a tooth has tooth decay (dental caries).

Provided herein in some aspects are compositions, combinations and methods that contain or use polypeptides that include the polypeptide of SEQ ID NO:1 (referred to herein as “Polypeptide Q”), and polypeptides that include a consecutive sequence of amino acids that is 80% or more, or 90% or more identical to a corresponding consecutive sequence of amino acids of Polypeptide Q. For example, a consecutive sequence of amino acids of a polypeptide of a composition provided herein, or used in a method provided herein, can have at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% or more amino acid sequence identity to a corresponding consecutive sequence of amino acids of Polypeptide Q or at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% or more amino acid sequence identity to a corresponding consecutive sequence of amino acids of Polypeptide Q. In some aspects, a polypeptide is an isolated and/or purified polypeptide, a recombinant polypeptide or a synthetically produced polypeptide.

The polypeptides can be isolated or otherwise obtained by methods known to those of skill in the art and/or provided herein. For example, the polypeptides can be generated recombinantly or produced using synthetic processes, such as chemical peptide synthesis methods. In addition, for the polypeptides that have a consecutive sequence of amino acids that bears 80% or more or 90% or more sequence identity to a corresponding consecutive sequence of amino acids of Polypeptide Q, the modified polypeptides and encoding nucleic acid molecules can include conservative or radical (non-conservative) amino acid substitutions, insertions or deletions.

Such amino acid(s) additions include tags or other moieties, for example, to aid in detection or affinity purification of the polypeptide. Examples include, but are not limited to, amino acid sequences that can serve as an epitope tag or other detectable marker. Particular non-limiting examples of such sequences include a His tag e.g.,

6xHis, or a Flag Tag, which are described further in the Examples herein.

The polypeptides provided herein can be used in methods, e.g., for the treatment of a disease or condition susceptible to, associated with and/or accompanied by infection, a tissue, such as animal (e.g., human) tissue, and/or tissue (e.g., surface tissue) injury or damage, including, for example, wounds, sores or burns in or on a subject, or for removing biofilm, or treating (e.g., disinfecting) a surface, e.g., in industrial, dental or health care settings.

Compositions and Combinations

Certain aspects of the compositions and combinations provided herein are now described. In some aspects, provided are compositions and combinations for treating a disease or condition susceptible to, characterized, associated with and/or accompanied by infection, e.g. microbial infection. The microbial infections can be associated with, for example, biological tissues (e.g., human and non-human animal tissues), such as, for example, the mucosa, e.g., peptidic ulcers in the stomach lining or infections associated with lung mucosa in cystic fibrosis or tuberculosis, or the infections can be associated with tissue injury or damage, for example, wounds or sores resulting from a disease or condition. Also provided are compositions and combinations for treating, e.g., decontaminating /disinfecting surfaces, for example, in industrial, dental or health care settings. In certain aspects, the compositions and combinations provided herein can kill, inhibit the growth of, or otherwise reduce or eliminate microbes that are associated with infections, wounds or sores, or microbes that are associated with certain surfaces such biological surfaces (e.g., surface of a living tissue) and surfaces of inanimate objects, such as in industrial, dental or health care settings. In some aspects, the compositions and combinations provided herein can render the microbes susceptible to traditional approaches, e.g., the use of antibiotics, antifungal agents, antiviral agents, antiseptics and/or oxidizing biocides that can kill the microbes and/or inhibit their growth and/or reduce the number of viable microbes or eliminate them, e.g., from a surface. For example, in subjects having diabetic sores associated with diabetes, e.g., diabetes mellitus, treatment with the compositions provided herein can increase the potency of other treatments, e.g., antibiotics, by providing access to the underlying tissues in the sore. In some aspects, the compositions and combinations provided herein can reduce the impact of viruses, such as the viruses responsible for COVID-19, shingles, warts, and cold sores.

The compositions and combinations provided herein can include, and the methods provided herein can use, one or more polypeptides selected from among the polypeptide of SEQ ID NO:1 (referred to herein as “Polypeptide Q”), and polypeptides that include a consecutive sequence of amino acids that is 80% or more, or 90% or more identical to a corresponding consecutive sequence of amino acids of Polypeptide Q. For example, a consecutive sequence of amino acids of the polypeptides in the compositions provided herein can have at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% or more amino acid sequence identity to a corresponding consecutive sequence of amino acids of Polypeptide Q or at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% or more amino acid sequence identity to a corresponding consecutive sequence of amino acids of Polypeptide Q. In certain aspects, the polypeptide is an isolated and/or purified, recombinant or synthetically produced polypeptide. A recombinant polypeptide is one that is produced using genetic recombination/engineering technologies and can involve heterologous expression of a polynucleotide encoding the polypeptide in a host cell system, e.g., heterologous host cell. A synthetically produced polypeptide is one that is generated using synthetic chemistry methods. The compositions and combinations provided herein can be pharmaceutical compositions or combinations, e.g., for the treatment of diseases or conditions susceptible to, characterized, associated with and/or accompanied by infection, e.g. microbial infection, and tissue injury or damage such as wounds, sores or burns in or on a subject, or they can be compositions or combinations for removing biofilm and/or treating (e.g., disinfecting) surfaces, e.g., in industrial, dental or health care settings.

The compositions and combinations provided herein and/or one or more polypeptide components of the compositions and combinations described herein can, in certain aspects, have microbicidal activity and/or microbiostatic activity. In certain aspects, the microbes are bacteria, fungi or viruses and the compositions and combinations provided herein and/or one or more polypeptide components of the compositions provided herein can have bactericidal activity and/or bacteriostatic activity, fungicidal and/or fungistatic activity, viricidal activity, virus inactivation activity and/or can reduce the impact of viral infections.

In aspects, the compositions and combinations provided herein and/or one or more polypeptide components of the compositions and combinations described herein can have biofilm removal activity and/or enzyme activity. In some embodiments, the enzyme activity includes a hydrolase activity, such as, for example, a hydrolase activity that acts on carboxylic ester bonds, e.g., an esterase, such as, for example, a serine esterase. In some aspects, the enzyme activity includes a cutinase activity. As described elsewhere herein, biofilms contain an attached community of microorganisms embedded in an exopolymer matrix that often persists despite attempts with traditional approaches designed to kill free-floating microorganisms because biofilms often are resistant to such treatments, e.g., with antibiotics, antiseptics, and oxidizing biocides. In addition, biofilms often confer immune resistance or create barriers to treatment of the underlying disease or condition. Thus, in certain aspects, the compositions and combinations provided herein are for removing biofilm barriers and increasing the potency of other therapeutically active agents or surface treatment agents for treating a surface or treating an underlying disease or condition, or an infection, wound or sore associated with an underlying disease or condition. The compositions and combinations having biofilm removal activity, as provided herein, also can, in certain aspects, include additional agents for biofilm removal, such as those described, for example, in WO/2006031554, WO/2001098214, WO/1998026807, WO/2004041988, WO/1999014312 and WO/2001053010. In certain aspects, the compositions and combinations provided herein and/or one or more polypeptide components of the compositions and combinations provided herein can have biofilm removal activity and one or both of microbicidal activity and microbiostatic activity, for example, bactericidal activity and/or bacteriostatic activity. In aspects, any of the compositions, such as pharmaceutical compositions, or compositions for treating a surface and/or removing biofilm provided herein, or combinations provided herein, can include one or more additional surface treatment agents, and/or therapeutically active agents for treating a surface or an underlying disease or condition, or for treating an infection, wound or sore associated with the underlying disease or condition.

The polypeptides contained in the compositions provided herein can be isolated from a microbial organism, such as, for example, a bacterium or fungus. Thus, in certain aspects, the compositions provided herein and/or one or more polypeptide components of the compositions provided herein can be thermally stable.

Methods for production and purification of proteins such as Polypeptide Q for use in the compositions, including pharmaceutical compositions, and methods provided herein are known in the art (see, e.g., Tan etai, Biomed. Res. Int., Article ID 574398 (2009)). In addition, for polypeptide components of the compositions and combinations provided herein that have a consecutive sequence of amino acids that bears 80% or more, or 90% or more sequence identity to a corresponding consecutive sequence of amino acids of Polypeptide Q, the modified polypeptides and encoding nucleic acid molecules can be produced by standard recombinant DNA techniques known to one of skill in the art. Any method known in the art to effect mutation of any one or more amino acids in a target protein, e.g., Polypeptide Q, can be employed. Methods can include standard site- directed or random mutagenesis of encoding nucleic acid molecules, or solid phase polypeptide synthesis methods. For example, nucleic acid molecules encoding a Polypeptide Q polypeptide can be subjected to mutagenesis, such as random mutagenesis of the encoding nucleic acid, error-prone PCR, site-directed mutagenesis, overlap PCR, gene shuffling, or other recombinant methods. The nucleic acids encoding the polypeptides can then be introduced into a host cell to be expressed heterologously. Hence, also provided herein are nucleic acid molecules encoding any of the polypeptides of the compositions and combination provided herein. In some aspects, the polypeptides of the compositions provided herein can be produced synthetically, such as by using solid phase or solution phase peptide synthesis.

Polypeptides such as Polypeptide Q also can be obtained by methods well known in the art for recombinant protein expression and purification. An example of a method for recombinant expression and purification of Polypeptide Q is provided in Example 1A and Example 1 B. Any method known to those of skill in the art for identification of nucleic acids that encode desired genes can be used. Any method available in the art can be used to obtain a full length (/.e., encompassing the entire coding region) cDNA or genomic DNA clone encoding a polypeptide provided herein, such as from a cell or tissue source. Modified Polypeptide Q polypeptides, such as those bearing 80% or more, or 90% or more consecutive amino acid sequence identity with a corresponding consecutive amino acid sequence in Polypeptide Q, can be engineered from a wildtype polypeptide, such as by site-directed mutagenesis.

The polypeptides can be cloned or isolated using any available methods known in the art for cloning and isolating nucleic acid molecules. Such methods include PCR amplification of nucleic acids and screening of libraries, including nucleic acid hybridization screening, antibody-based screening and activity-based screening.

Methods for amplification of nucleic acids can be used to isolate nucleic acid molecules encoding a desired polypeptide, such as Polypeptide Q, including for example, polymerase chain reaction (PCR) methods. A nucleic acid containing material can be used as a starting material from which a desired polypeptide-encoding nucleic acid molecule can be isolated. Nucleic acid libraries also can be used as a source of starting material. Primers can be designed to amplify a desired polypeptide. For example, primers can be designed based on expressed sequences from which a desired polypeptide is generated. Primers can be designed based on back-translation of a polypeptide amino acid sequence. Nucleic acid molecules generated by amplification can be sequenced and confirmed to encode a desired polypeptide. A polynucleotide encoding Polypeptide Q is provided herein as SEQ ID NO:2.

A polynucleotide encoding a polypeptide provided herein, e.g., Polypeptide Q, can also be synthetically produced using methods known in the art, such as, for example, synthetic chemistry based polynucleotide synthesis methods. Additionally, the polynucleotides encoding a polypeptide provided herein can be modified for any reason, including, for example, to facilitate or enhance expression in a recombinant host. For example, a polynucleotide sequence encoding a polypeptide described herein can be modified to optimize the codons encoding the amino sequence of the desired polypeptide without altering the amino sequence. The nucleotide sequence of a polynucleotide encoding Polypeptide Q which is codon optimized for insertion in plasmid DNA is provided herein in SEQ ID NO:3.

Additional nucleotide sequences can be joined to a polypeptide-encoding nucleic acid molecule, including linker sequences containing restriction endonuclease sites for the purpose of cloning the synthetic gene into a vector, for example, a protein expression vector or a vector designed for the amplification of the core protein coding DNA sequences. Furthermore, additional nucleotide sequences specifying functional DNA elements can be operatively linked to a polypeptide-encoding nucleic acid molecule. Examples of such sequences include, but are not limited to, promoter sequences designed to facilitate intracellular protein expression, and secretion sequences, for example heterologous signal sequences, designed to facilitate protein secretion. Such sequences are known to those of skill in the art. Additional nucleotide residues sequences such as sequences of bases specifying protein binding regions also can be linked to enzyme-encoding nucleic acid molecules. Such regions include, but are not limited to, sequences of residues that facilitate or encode proteins that facilitate uptake of an enzyme into specific target cells, or otherwise alter pharmacokinetics of a product of a synthetic gene.

In addition, tags or other moieties can be added, for example, to aid in detection or affinity purification of the polypeptide. For example, additional nucleotide residues sequences such as sequences of bases specifying an epitope tag or other detectable marker also can be linked to enzyme-encoding nucleic acid molecules. Non-limiting examples of such sequences include nucleic acid sequences encoding a His tag e.g., 6xHis, or a Flag Tag.

In certain aspects, the polypeptide encoded by the polynucleotides provided herein exhibits biofilm removal activity and/or enzyme activity. In some aspects, a polynucleotide provided herein encodes a consecutive sequence of amino acids that has at least 80%, 81%,

82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% or more amino acid sequence identity to a corresponding consecutive sequence of amino acids of SEQ ID NO: 1, or at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% or more amino acid sequence identity to a corresponding consecutive sequence of amino acids of SEQ ID NO:1. In some aspects, such a polynucleotide is at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identical to the sequence of nucleotides set forth in SEQ ID NO:2 or SEQ ID NO:3, or at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identical to the sequence of nucleotides set forth in SEQ ID NO:2 or SEQ ID NO:3.

The identified and isolated nucleic acids can then be inserted into an appropriate cloning vector. A large number of vector-host systems known in the art can be used. Possible vectors include, but are not limited to, plasmids or modified viruses, but the vector system must be compatible with the host cell used. Such vectors include, but are not limited to, bacteriophages such as lambda derivatives, or plasmids such as pCMV4, pBR322 or pUC plasmid derivatives or the Bluescript vector (Stratagene, La Jolla, CA). Other expression vectors include the HZ24 expression vector. The insertion into a cloning vector can, for example, be accomplished by ligating the DNA fragment into a cloning vector which has complementary cohesive termini. Insertion can be effected using TOPO cloning vectors (Invitrogen, Carlsbad, CA). If the complementary restriction sites used to fragment the DNA are not present in the cloning vector, the ends of the DNA molecules can be enzymatically modified. Alternatively, any site desired can be produced by ligating nucleotide sequences (linkers) onto the DNA termini; these ligated linkers can contain specific chemically synthesized oligonucleotides encoding restriction endonuclease recognition sequences. In an alternative method, the cleaved vector and protein gene can be modified by homopolymeric tailing. Recombinant molecules can be introduced into host cells via, for example, transformation, transfection, infection, electroporation and sonoporation, so that many copies of the gene sequence are generated.

For recombinant expression of a protein such as Polypeptide Q, the nucleic acid containing all or a portion of the nucleotide sequence encoding the protein can be inserted into an appropriate expression vector, i.e., a vector that contains the necessary elements for the transcription and translation of the inserted protein coding sequence. The necessary transcriptional and translational signals also can be supplied by the native promoter for enzyme genes, and/or their flanking regions. Also provided are vectors that contain a nucleic acid encoding Polypeptide Q and variants that bear 80% or more, or 90% or more sequence identity thereto, as provided in the compositions described herein. Cells containing the vectors also are provided. The cells include eukaryotic and prokaryotic cells, and the vectors are any suitable for use therein.

Prokaryotic and eukaryotic cells containing the vectors are provided. Such cells include bacterial cells, yeast cells, fungal cells, Archea, plant cells, insect cells and animal cells. The cells are used to produce a protein thereof by growing the above-described cells under conditions whereby the encoded polypeptide is expressed by the cell, and recovering the expressed polypeptide.

Provided are vectors that contain a sequence of nucleotides that encodes Polypeptide Q, or a polypeptide having a consecutive sequence of amino acids that is 80% or more, or 90% or more identical to a corresponding consecutive sequence of amino acids of Polypeptide Q. The vectors can be selected for expression of the polypeptide in the cell or such that the polypeptide is expressed as a secreted polypeptide.

A variety of host-vector systems can be used to express the coding sequences of the polypeptides of the compositions provided herein. These include, but are not limited to, mammalian cell systems; insect cell systems; microorganisms such as yeast containing yeast vectors; or bacteria transformed with bacteriophage, DNA, plasmid DNA, or cosmid DNA. The expression elements of vectors vary in their strengths and specificities. Depending on the host-vector system used, any one of a number of suitable transcription and translation elements can be used.

Any methods known to those of skill in the art for the insertion of DNA fragments into a vector can be used to construct expression vectors containing a chimeric gene containing appropriate transcriptional/translational control signals and protein coding sequences. These methods can include in vitro recombinant DNA and synthetic techniques and in vivo recombinants (genetic recombination). Expression of nucleic acid sequences encoding protein, or domains, derivatives, fragments or homologs thereof, can be regulated by a second nucleic acid sequence so that the genes or fragments thereof are expressed in a host transformed with the recombinant DNA molecule(s). For example, expression of the polypeptides can be controlled by any promoter/enhancer known in the art.

Further non-limiting examples of compositions also include concentrations of polypeptide(s) provided herein, e.g., Polypeptide Q and/or variants that bear 80% or more, or 90% or more sequence identity thereto, of about 10% or less, 9% or less, 8% or less, 7% or less, 6% or less, 5% or less, 4% or less, 3% or less, 2% or less, 1% or less, 0.5% or less, or 0.25% or less weight/volume of the one or more polypeptides.

In certain aspects, the compositions and combinations provided herein have biofilm removal activity and the concentrations of polypeptide(s) in the compositions or combinations provided herein are in an amount that reduces the amount of biofilm in a subject or on a surface by about 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more, up to 100%. In vitro assays using biofilm-specific staining to measure the amount of biofilm are known to those of skill in the art. An example of an in vitro assay for measuring biofilm removal activity is demonstrated in Example 2. For example, biofilm removal can be measured using a crystal violet assay (see, e.g., US Patent No. 8,597,927). Samples are immersed in a solution of Crystal Violet (0.31% w/v) for ten minutes prior to rinsing three times in phosphate buffered saline (PBS) to remove unbound stain. Bound stain retained by a biofilm is extracted with 95% ethanol and the absorbance of the Crystal Violet/ethanol solution is read at 540 nm. Percent removal of a biofilm is calculated as [(1-Fraction remaining biofilm)x100]. Fraction remaining biofilm is calculated by subtracting the absorbance of the medium + enzyme solutions from the absorbance of the solutions extracted from the enzyme treated biofilms, divided by the difference in absorbance from that of untreated control biofilms minus the absorbance of the growth medium only.

Other biofilm-specific stains that can be used include, but are not limited to, Film Tracer (Thermo Fisher Scientific, Inc.), Safranin, Congo Red, Acridine Orange and histochemical staining. Biofilm removal also can be assessed by suspending cells from a treated biofilm in a buffer such as phosphate buffered saline (PBS) by plating cells on a suitable nutrient containing growth medium and counting the number of cells that grow on the medium. Reduction in viable cell count can be determined by comparison with the number of cells that grow from a suspension prepared from a control untreated biofilm.

An example of an in vitro assay for measuring biofilm removal activity is demonstrated in Example 2. In vivo models for measuring biofilms also are known in the art (see, e.g., Seth et ai, J. Surg. Res., 178:330-338 (2012), and documents cited therein).

Methods

Certain aspects of the methods provided herein are now described. In certain aspects, provided herein are methods of treating a disease or condition in a subject that includes administering, to a subject in need thereof, a composition, e.g., pharmaceutical composition or a composition for removing biofilm or treating a surface, provided herein or a combination, provided herein. In some aspects, the methods include administering a therapeutically effective amount of a composition, e.g., pharmaceutical composition, or combination provided herein. In some aspects, the disease or condition is one that is susceptible to, associated with and/or accompanied by an infection, tissue, such as animal (e.g., human) tissue, and/or tissue (e.g., surface tissue) injury or damage, including, for example, wounds, sores or burns in or on a subject. In some aspects, the disease or condition is accompanied by or associated with tissue, including, for example, epithelial tissue, connective tissue, or tissue membranes (e.g., mucous membranes, cutaneous membranes and serous membranes). In certain aspects, the disease or condition can be associated with mucosa, a wound, sore, ulcer or infection. Non-limiting examples of diseases or conditions that can be treated using the pharmaceutical compositions provided herein are described below:

Cystic Fibrosis

Cystic fibrosis, a genetically inherited disease, is caused by the mutation of a gene that produces an electrolyte transfer protein. The consequence of the mutation affects a multitude of organ systems. However, the tissues that are most directly affected are those that secrete mucus or have mucus membranes. Adverse consequences occur with tissues that are associated with the respiratory system i.e., lungs and airway passage tissues. In response to the genetic defect, the host produces secretions to counteract the ionic imbalance. These secretions in response to the disease allow opportunistic infections to develop, which causes additional fluid and mucus to infiltrate the respiratory system from the host. The infectious bacteria and the associated bacterial biofilm add additional mucus and fluid at the site. In addition, the principal bacterial pathogen associated with the opportunistic infection is Pseudomonas aeruginosa, which often mutates to a mucoid form that is a prolific producer of alginate biofilm and further exacerbates the disease condition. The result is an accumulation of copious amount of mucus, fluid and biofilm material which affects not only the respiratory system, but the entire host.

The current treatment of cystic fibrosis involves a dual approach to: 1) promote and facilitate the removal of mucus and secretions from the respiratory tract and; 2) control the infection that is associated with the disease. The infection, with the bacteria's production of a biofilm, obstructs the host's defenses, shields the bacteria from the killing action of antibiotics and increases the viscosity of the mucus, making it increasingly difficult for the patient to expectorate the interfering mucus. Thus, provided herein are compositions, e.g., pharmaceutical compositions, and combinations, e.g., pharmaceutical combinations, that control the infection associated with cystic fibrosis and increase responsiveness, e.g., to the action of antibiotics. Infection

Wound infection can lead to the interruption of several processes along the wound healing pathway. Bacteria produce inflammatory mediators that inhibit the inflammatory phase as well as epithelialization phase of wound healing. Bacteria in an infected wound cause cell death, which will lead to an increase in local inflammation response and prolonged acute inflammatory phase. The presence of necrotic tissue prevents the ingrowth of new tissue. In addition, necrotic tissue also serves as a culture for bacterial proliferation, therefore, leading to a vicious pathologic cycle. Thus, provided herein are compositions, e.g., pharmaceutical compositions, and combinations, e.g., pharmaceutical combinations, that treat wound infection or increase the susceptibility of wound infection to traditional treatment approaches, e.g., the action of antibiotics.

Also provided herein are compositions, e.g., pharmaceutical compositions, and combinations, e.g., pharmaceutical combinations, for the treatment of infections, such as tuberculosis or COVID-19.

Ischemic conditions

Ischemia is a condition that results in chronic non-healing wounds and can be seen in arterial insufficiency, venous hypertension, and pressure injuries.

Ischemic condition due to arterial insufficiency

In subjects with arterial insufficiency, arterial blood flow to the tissue is diminished, leading to a decrease in the delivery of oxygen and nutrients to the wound, and impairment in the removal of metabolic waste products from the wound. Limb threatening ischemia develops when blood flow to the extremity is insufficient to meet the metabolic demands of the tissue, manifesting as rest pain or non-healing wounds. Due to the chronic deficiency of oxygen and nutrients, the skin of the affected limb is not able to maintain normal tissue architectures. Clinically, this is manifested as shiny skin surface with paucity of hair. The metabolic demands to maintain intact skin is higher than the metabolic demands to heal a wound. A simple cut or abrasion on the skin caused by poor fitting shoes can alter the balance of metabolic demand, leading to a chronic wound. The most common cause of arterial insufficiency ulcers is obstruction of large and medium-size arteries caused by atherosclerosis. Other conditions that affect small arteries such as vasculitis, thromboangiitis obliterans, and scleroderma can also cause ischemic ulcers. Provided herein are compositions, e.g., pharmaceutical compositions, and combinations, e.g., pharmaceutical combinations, that treat arterial insufficiency ulcers or increase the susceptibility of these ulcers to traditional treatment approaches.

Ischemic condition due to venous hypertension

In subjects with chronic deep vein thrombosis, arteriovenous fistula or venous insufficiency, hydrostatic pressure is built up in the venous system leading to venous hypertension. This results in the loss of pressure gradient between the arterioles and the venules, leading to slowing of the movement of blood within the capillaries. This sluggish movement of blood results in sequestration of erythrocytes and leukocytes within the capillaries, and the elevation of hydrostatic pressure within the capillaries results in capillary leak. The fibrinogen leaked from the capillaries of the dermis form a fibrin cuff. This fibrin cuff, in combination with tissue edema, result in decreased oxygen permeability, leading to tissue hypoxia and impaired wound healing. The leukocytes that are trapped in the capillaries adhere to the endothelium and release inflammatory mediators and reactive oxygen metabolites. These, in turn, cause endothelial damage, obliteration of the capillaries, and subsequent tissue ischemia. Capillaries of subjects with venous stasis are also occluded by microthrombi that, in turn, reduce oxygen and nutrition to the tissue, predisposing to ulcer formation. Provided herein are compositions, e.g., pharmaceutical compositions, and combinations, e.g., pharmaceutical combinations, that treat venous hypertension ulcers or increase the susceptibility of these ulcers to traditional treatment approaches.

Ischemic condition due to pressure injuries

The development of pressure injuries is caused by a combination of pressure and shear force. Pressure is defined as force per unit area. Therefore, smaller areas such those over bony prominences sustain higher pressure and are at higher risk for development of pressure injuries. When the pressure applied to the skin is in excess of arteriolar pressure, oxygen and nutrient delivery to the tissue is shut off, resulting in tissue hypoxia and accumulation of waste products and free radicals. In animal models, pressure in excess of 70 mm of Hg for two hours result in irreversible tissue damage. Although critical duration of ischemia can vary among individuals and clinical situations, as a rule of thumb, pressure injuries can develop within 1 to 4 hours of sustained pressure load. Beside the externally applied pressure, the individual tolerance of tissue to ischemia also plays an important role. Evidence suggests that subjects with peripheral arterial occlusive disease are at higher risk for developing pressure ulcers. Critically ill patients with higher disease severity scores such as Acute Physiology and Chronic Health Evaluation (APACHE) score, are more likely to develop pressure ulcers due to global hypoperfusion of tissue, predisposing them to ischemic pressure injuries. Extensive tissue damage can sometimes occur with little evidence of superficial injury. Shear force occurs when there is lateral displacement of the tissue, usually by gravity or by subjects being dragged across an external surface. In these situations, deeper tissues such as bone, muscles, and subcutaneous fat are shifted laterally while the dermis remain fixed through contact with external surfaces. The result of this lateral displacement is injury to the tissue, blood vessels, and lymphatics. Excessive moisture in the form of perspiration, urine, and feces can lead to maceration of the superficial tissue and changes in the cutaneous chemical environment. Although excessive moisture by itself does not directly cause pressure injuries, it can lead to impaired wound healing and promote the generation of chronic wounds. Provided herein are compositions, e.g., pharmaceutical compositions, and combinations, e.g., pharmaceutical combinations, that treat wounds occurring as a result of pressure injuries or increase their susceptibility to traditional treatment approaches.

Metabolic Conditions

Certain metabolic conditions that contribute to the development of non-healing wounds.

Diabetes Mellitus

There are several factors related to diabetes that can contribute to the pathogenesis of diabetic foot ulcers. In diabetic neuropathy, damage to the sensory, motor, and autonomic nerve fibers affects peripheral sensation, motor innervation of small muscles in the foot, and fine vasomotor control of the pedal circulation. In sensory neuropathy, the loss of protective sensation leads to lack of awareness of sustained pressure on the tissue or injury to the tissue. Motor neuropathy usually affects the innervation of the small intrinsic muscles of the feet, resulting in the unopposed action of the larger muscles in the anterior tibial compartment. This leads to subluxation of the proximal metatarsal-phalangeal joints, giving the feet the appearance of claw toes. Consequently, the pressure is redistributed abnormally to the metatarsal heads, where reactive thickening of the skin (callus) forms. Ischemic necrosis of the tissue under the callused skin eventually leads to breakdown of the skin, resulting in a neuropathic ulcer with the punched-out appearance commonly under the metatarsal heads. Autonomic neuropathy is characterized by a lack of autonomic tone in the arteriolar and capillary circulation, causing shunting of blood from the arterioles directly to the veins, thus bypassing the tissue that needs the nutrients. Although the feet may have bounding pulses and distended veins, the tissue can lack the perfusion needed for healing and to fight infection. Additionally, the loss of autonomic innervation to the sweat glands of the feet results in dry, scaly skin that can crack easily, allowing bacteria to penetrate. The Charcot foot is a later complication of diabetes and is characterized by collapse of the arch of the midfoot. Osteopenia due to arteriolar-venous shunting of autonomic neuropathy combined with small intrinsic muscle wasting, lead to loss of structural integrity of the bone. Stress and minor trauma can induce fracture of a weakened bone, putting more stress on the adjacent weakened bones, and the cycle repeats, ultimately leading to gross deformity. The resulting abnormal bony prominences that form greatly increase the risk of ulceration. Provided herein are compositions, e.g., pharmaceutical compositions, and combinations, e.g., pharmaceutical combinations, that treat diabetic sores or ulcers or increase the susceptibility of these sores or ulcers to traditional treatment approaches.

Malnutrition

Fatty acids are essential for the inflammatory phase of wound healing as they provide the arachidonic acid substrate for eicosanoid synthesis. Proteins are required for the proliferation of fibroblasts and the synthesis and deposition of collagen. Proteins are also required for important immunologic functions such as phagocytic activity of macrophages, T-cell function, and compliment and antibody production. Malnutrition can impair wound healing by prolonging the inflammatory phase and by reducing the proliferation of fibroblasts and deposition of collagen. Malnutrition is associated with increased risk of wound infection, which has deleterious effects on wound healing. Provided herein are compositions, e.g., pharmaceutical compositions, and combinations, e.g., pharmaceutical combinations, that treat wounds associated with malnutrition or increase the susceptibility of these wounds to traditional treatment approaches.

Immunosuppression

Systemic immunosuppression can contribute to the development of non-healing wounds. Corticosteroids have been shown to interfere with all major steps of the wound healing process in both animals and human studies. In the inflammatory phase, corticosteroid decreases the expression of cytokines that are responsible for the recruitment of inflammatory cells, as well as the expression of adhesion molecules responsible for adhesion and migration of granulocytes. In the proliferative phase, corticosteroids reduce the levels of transforming growth factor-b and keratinocyte growth factor, which attenuates fibroblast proliferation and wound epithelization respectively. In the remodeling phase, corticosteroids impair collagen accumulation as well as collagen turnover. Clinically, subjects who are on chronic corticosteroids that undergo surgery have significantly increased infection rate as well as wound dehiscence rate. Immunosuppressive agents can suppress the expression of several inflammatory mediators that are involved in the wound healing process. Immunosuppressive agents inhibit the proliferation of immune cells and may blunt the inflammatory phase of wound healing. Sirolimus, an immunosuppressive agent that inhibits the threonine kinase known as mammalian target of rapamycin (mTOR), is associated with a significantly higher wound complication rate compared to other common immunosuppressive agents.

Chemotherapeutic agents, particularly those that target vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR), can have detrimental effects on wound healing. Inhibition of VEGF results in the suppression of angiogenesis, which is an important part of wound healing. Epidermal growth factor receptor inhibitors can negatively impact wound healing by inhibiting epithelialization. Provided herein are compositions, e.g., pharmaceutical compositions, and combinations, e.g., pharmaceutical combinations, that treat wounds associated with immunosuppression or increase the susceptibility of these wounds to traditional treatment approaches.

Radiation

Ionized radiation used in the treatment of cancer can cause delay in wound healing. Sometimes, radiation injury results in chronic non-healing wounds. Ionizing radiation causes cellular damage by breaking the double-stranded cellular DNA and releasing free radicals. This effect is most profound in cells undergoing DNA replication and mitosis. The resulting effect is apoptosis and cellular necrosis. Radiation also can cause eccentric myointimal proliferation in the small arteries and arterioles, which may cause luminal thrombosis and obstruction. This results in ischemia to the tissue which can progress to tissue necrosis. Provided herein are compositions, e.g., pharmaceutical compositions, and combinations, e.g., pharmaceutical combinations, that can arrest or inhibit delays caused by radiation treatments in the healing of wounds or increase the susceptibility of treating such delays using traditional approaches.

Decontamination/Disinfection of Surfaces

In certain aspects, provided herein are methods of decontaminating/disinfecting a surface using the compositions provided herein. A "surface," as used herein, refers to a structure having sufficient mass to allow for attachment of a biofilm. Hard surfaces include, but are not limited to, metal, glass, ceramic, wood, mineral (e.g., rock, stone, marble, granite), aggregate materials such as concrete, plastic, composite material, hard rubber material, and gypsum. A hard material can be finished with enamel and/or paint. Hard surfaces are found, for example, in water treatment and storage equipment and tanks, dairy and food processing equipment and facilities, medical equipment and facilities, e.g., surgical instruments, permanent and temporary implants, and industrial pharmaceutical equipment and plants. Soft surfaces include, but are not limited to, hair and textiles. Porous surfaces can be biological surfaces, including, but not limited to, skin, keratin, mucous membranes, and internal organs. Porous surfaces can also be found in certain ceramics as well as in membranes that are used for filtration. Other surfaces include, but are not limited to, ship hulls and swimming pools.

Exemplary Amino Acid and Nucleotide Sequences

Examples

The examples set forth below illustrate certain embodiments and do not limit the technology. Certain examples set forth below utilize standard recombinant DNA, membrane vesicle / liposome preparation and other biotechnology protocols known in the art.

Example 1A: Expression and Purification of Polypeptide Q

DNA (SEQ ID NO:3) which is a codon optimized sequence encoding Polypeptide Q (SEQ ID NO:1) was introduced into a plasmid for recombinant expression of Polypeptide Q, followed by purification of the recombinantly expressed Polypeptide Q, as follows:

A. Transformation of Rosetta cells with Polypeptide Q DNA A 50 mI aliquot of Rosetta (DE3) pLysS cells was transformed with 50 ng of pET28b(+)- Polypeptide Q plasmid DNA (a plasmid construct containing the sequence of polynucleotides, SEQ ID NO:3, which encodes Polypeptide Q) by heating on a mini heat block at 42 °C for 90 secs. The transformation solution was chilled on ice for 2 mins. A volume of 445 mI of SOC media was added to the cell suspension, which was then incubated at 37 °C for 1 hour on a tabletop incubator with shaking at 225 rpm. The cells were pelleted by spinning at 6,000 rpm for 6 minutes on a tabletop centrifuge. A volume of 300 mI of supernatant was extracted and discarded, and the cell pellet was then resuspended in the remaining 200 mI of media. The cell suspension (200 mI) was added to the center of a LB-agar plate containing a final concentration of 30 pg/ml kanamycin and 34 pg/ml chloramphenicol. The cell suspension was spread evenly on the plate using a sterilized glass cell spreader. The plate was allowed to dry for 10 minutes and then incubated overnight at 37 °C.

B. Picking colonies and establishing an overnight culture

3 medium sized colonies were picked with a sterile 200 pi pipette tip and delivered to 100 ml of LB broth containing a final concentration of 30 pg/ml kanamycin and 34 pg/ml chloramphenicol in a 500 ml Erlenmeyer flask. The overnight culture was incubated at 37 °C with shaking at 225 rpm for > 16 hours.

C. Back dilution of overnight culture and induction of recombinant gene expression

A volume of 20 ml of the saturated overnight culture was back diluted into 1 L Erlenmeyer flasks containing 500 ml fresh LB broth dosed with 30 pg/ml kanamycin and 34 pg/ml chloramphenicol. A total of 8 flasks (4 liters) was prepared from 100 ml of overnight culture (10 ml of overnight culture/500 ml media). The flasks were incubated at 37 °C shaking at 225 rpm until the absorbance at 600 nm (Oϋboo) was between 0.6 and 1.0 (approximately 2.5-3.5 hrs). IPTG was added to the overnight cultures in the 8 Erlenmeyer flasks to a final concentration of 1 mM. The flasks were transferred to a platform shaker at room temperature for shaking overnight (> 16 hrs) at 225 rpm. After induction, the absorbance at 600 nm of 1 ml of the cells was measured on a UV-Vis spectrophotometer and recorded. On average, cell cultures expressing Polypeptide Q displayed a 60-65% reduction in OD₆oo-

D. Purification of 6xHis-Polypeptide Q from Rosetta cell culture supernatant The 4 L of cell suspension was aliquoted evenly into six 500 ml centrifuge bottles (250 ml per bottle) and centrifuged at 4,000 x g for 20 mins. Centrifugation was repeated until all 4 L were spun down and cells were separated from the supernatant. The cells were discarded, and the supernatant was pooled in 1 L aliquots in four clean 1 L bottles. A total volume of 10 ml of 3 M imidazole was added to each 1 L bottle to bring the final imidazole concentration to 30 mM. Bed volumes (15 ml) of Ni-NTA resin were poured into two 3.175 cm x 53.34 cm glass columns and 5 ml of Ni-NTA was poured into two 3.175 cm x 33.02 cm glass columns. All columns were fitted with stopcocks and pre equilibrated in RODI water. A volume of -250 ml of supernatant was poured over the two 15 ml Ni-NTA columns. The smaller 5 ml columns were positioned in tandem under the larger 15 ml columns. All pre-eluate solutions run over 15-ml and 5-ml resin beds was collected and pooled in a 4 L plastic beaker. When the drip rate dropped to <1 drop/3 seconds, the flow was halted using the stopcock. The resin bed was mixed by pipetting up and down using a pipette-gun fitted with a 25 ml serological pipette.

After the supernatant was loaded onto the columns, the resin beds were washed in 10 column volumes (CV) of wash buffer (20 mM sodium phosphate pH: 7.4, 300 mM NaCI, 30 mM imidazole) separately. After washing, the bound protein was eluted by running 1 CV of elution buffer (20 mM sodium phosphate pH: 7.4, 300 mM NaCI, 250 mM imidazole) over the resin bed. The elution step was repeated once for each column (a total of 8 elutions). The eluate from each column was collected in a separate 50 ml conical tube. A 30 pi sample was taken from each eluate, added to 10 pi of 4X reducing SDS-sample buffer and boiled at 95 °C for 10 min. on a mini heat block. The samples were cooled to room temperature and loaded onto a 4-20% gradient tris-glycine SDS- PAGE gel. One lane of each gel was loaded with 5 mI of a molecular weight standard diluted in 25 mI of 1X SDS-sample buffer (PageRuler Plus, Thermo Fisher Scientific, Inc., Waltham, MA) for molecular weight (MW) estimation. The gels were run at a constant 200V for approximately 45 min. and stained with AcquaStain protein dye (Bulldog Bio, Inc., Portsmouth, NH) overnight. The Ni-NTA eluates contain 2 prominent contaminants. The higher molecular weight contaminant resolves between the 70- and 100-kDa marker and the lower molecular weight contaminant resolves between the 10- and 15-kDa marker. The most intense band in the Ni-NTA eluates is ~25-kDa, consistent with the size of 6xHis-Polypeptide Q. E. Desalting/buffer exchanging Polypeptide Q eluates into sodium acetate, pH:

6.0 for differential protein precipitation and further purification of Polypeptide Q

Eluates were pooled and concentrated to a volume of 8 ml using a 10,000 Da MWCO centrifugal concentrator. The total volume of the Ni-NTA eluates was subsequently loaded 12 ml at a time into the concentrator and centrifuged at 6,000 x g for 20-30- minute intervals until the desired volume was reached. The filtrate was discarded as the retentate contained recombinant Polypeptide Q. All 8 ml of concentrated Ni-NTA eluate was loaded into a 10,000 Da MWCO dialysis cassette and dialyzed against 4 L of 25 mM sodium acetate, pH: 6.0 (no salt). The initial 4 L dialysis was conducted for 3 hours at 4 °C and the dialysis buffer was changed. The second 4 L dialysis was performed overnight at 4 °C (~16 hours).

Following dialysis, the protein solution was visibly turbid, indicating protein precipitation/aggregation. The dialysis buffer was changed 2 additional times with incubation periods of ~3 hours between changes. The turbidity of the solution remained constant through the remainder of the dialysis process. The protein solution was extracted from the interior of the dialysis cassette using a needle and syringe, transferred to a 50 ml conical tube and centrifuged at 29,097 x g for 20 minutes. The supernatant was recovered, and the protein pellet was resuspended in 400 pi of 25 mM sodium acetate, pH: 6.0 containing 50 mM NaCI. A 30 mI sample of the supernatant and the reconstituted pellet was combined with 10 mI of 4X reducing SDS-sample buffer respectively.

The samples were boiled at 95 °C for 10 mins on a mini heat block and 30 mI were run on a 4-20% tris-glycine gradient SDS-PAGE gel along with PageRuler Plus pre-stained ladder (as described above) at constant 200V for approximately 45 mins until the dye front reached the bottom of the gel. The gel confirmed that only the ~25 kDa band consistent with recombinant Polypeptide Q remained in the supernatant; all the contaminant bands along with -40-50% of the total amount of the Polypeptide Q protein were partitioned into the insoluble pellet fraction. Another round on a centrifugal concentrator was used to decrease the overall volume of the soluble Polypeptide Q sample to -1 ml. A volume of 25 mI of 2 M NaCI was added to the concentrated Polypeptide Q (for a final concentration of 50 mM NaCI) sample to stabilize the protein and prevent further aggregation. F. Estimation of 6xHis-Polypeptide Q protein concentration and dilution for Listeria monocytogenes biofilm removal assay

A combination of absorbance at 280 nm coupled with the predicted extinction coefficient and MW of 6xHis-Polypeptide Q, and the use of a 660 n assay reagent kit (Thermo Fisher Scientific, Inc., Waltham, MA) estimated the concentration of 6xHis-Polypeptide Q between 150 and 300 pg/ml. The biofilm removing ability of recombinant 6xHis- Polypeptide Q was tested in an in vitro assay against Listeria biofilms. A 100 pi volume of the 6xHis-Polypeptide Q sample was diluted 10-fold in 1-ml of enzyme diluent (25 mM Tris-HCI, pH: 7.5, 2.5 mM CaC , 2.75 mM MgC ). Both undiluted (in 25 mM sodium acetate, pH: 6.0, 50 mM NaCI) and diluted 6xHis-Polypeptide Q samples were used in the Listeria biofilm removal assay. Enzyme diluent and 25 mM sodium acetate, pH: 6.0 with 50 mM NaCI was provided as negative controls.

Example 1B: Expression and Purification of Polypeptide Q

A variant of Example 1A is as follows (only sections with differences are restated):

A volume of 20 ml of the saturated overnight culture was back diluted into 2x 1 L Erlenmeyer flasks containing 500 ml fresh LB broth dosed with kanamycin and chloramphenicol. The flasks were incubated at 37 °C shaking at 225 rpm until the absorbance at 600 nm (Oϋboo) was between 0.6 and 1.0 (approximately 2.5-3.5 hrs). IPTG was added to the overnight cultures in the 8 Erlenmeyer flasks to a final concentration of 1 mM. The flasks were transferred to a platform shaker at room temperature for shaking overnight (> 16 hrs) at 225 rpm. After induction, the absorbance at 600 nm of 1 ml of the cells was measured on a UV-Vis spectrophotometer and recorded. The supernatant was harvested when the OD₆oo dropped to -0.3.

D. Purification of 6xHis-Polypeptide Q from Rosetta cell culture supernatant

PMSF was added to the culture to a final concentration of 1 mM. The cell suspension was spun down. The supernatant was pooled and combined with 250 ml of 5x binding buffer (100 mM sodium phosphate pH: 7.4, 2.5 M sodium chloride, 200 mM imidazole). The diluted supernatant was filtered through a 1 L - 0.2 pm PES bottle top filter and split into 4 — 300 ml aliquots. Each aliquot was passed over 1 - 3.175 x 33.02 cm glass column containing a 5 ml resin bed of HisPur Ni-NTA resin at 4 °C. The flowthrough was collected in a separate container and a 30 pi sample was combined with 10 mI 1X Laemmli SDS sample buffer, boiled for 10 minutes and stored at room temperature for SDS-PAGE analysis. The lysate loaded resin was washed in 10 column volumes (50 ml) of 1x binding buffer. The bound protein was eluted in 5 ml of elution buffer. A total of 4 separate elution fractions were obtained from each column. A 30 mI sample of each elution fraction was combined with SDS sample buffer. SDS-PAGE analysis revealed that all fractions contained observable amounts of Polypeptide Q.

E. Desalting/buffer exchanging Polypeptide Q eluates into sodium acetate, pH:

The samples were dialyzed against 10 L of Tris buffer (50 mM Tris pH: 8.0, 150 mM NaCI) and concentrated to ~2 ml using a centrifugal concentrator. A Bradford assay determined the total protein concentration to be -0.5 mg/ml. Densitometry values indicated that the desired band contributed to -50% of the total protein in the sample. A total of 133.4 mI of the sample was combined with 866.6 mI of T ris buffer and used for biofilm removal analysis.

Example 2: Biofilm Removal Activity of Polypeptide Q

A modified version of the method presented by Djordjevic, Wiedmann, and McLandsborough ( Appl . Environ. Microbiol., 68(6):2950-2958, 2002) was used for measuring biofilm formation. An isolated Listeria monocytogenes colony was selected and transferred to 10 mL of liquid growth media at 37 °C overnight. The overnight culture (0.1 mL) was transferred to 10 mL of fresh growth media. The culture was vortexed and 100 pL volumes were transferred to eight columns of 6 PVC microtiter plate wells previously rinsed with 70% ethanol and air dried in a biological safety hood for 40 min. Each plate was loaded in triplicate, covered, and incubated at the appropriate temperature for 48 hrs.

Following incubation, the media was removed. Each well was washed 5 times with 100 pL of sterile deionized water and allowed to air dry for 40 mins. Negative control, undiluted 6xHis-Polypeptide Q samples or diluted 6xHis-Polypeptide Q samples as described in Example 1A, part F (150 pL) were added to each well and incubated at the desired temperature for either two or four hours. The samples were removed. Each well was washed 5 times with 100 pL of sterile deionized water and allowed to air dry for 40 min. Once dry, the wells were stained with a 0.1 % crystal violet solution (150 pL) for 45 min. Each well was washed 5 times with 100 pL of deionized water and allowed to air dry for 40 mins. Stained wells were de-stained for 1 hour with 200 pL of 95 % ethanol. Samples (100 pL) were taken from each well and transferred to a new PVC microtiter plate and the absorbance was read at 570 nm using a SpectraMax Pro 38496-well plate reader.

Results

Polypeptide Q exhibited biofilm removal activity. In Figure 1, the amount of biofilm, as measured by the absorbance at 570 nm due to biofilm-specific crystal violet staining, was significantly decreased in the presence of Polypeptide Q. The initial amount of biofilm showed an absorbance of about 1.0 at 570 nm. By comparison, the negative control treatment resulted in an absorbance of about 0.7 at 570 nm, and treatment with undiluted Polypeptide Q resulted in an absorbance measurement of about 0.4 at 570 nm. Measured in terms of percent biofilm removal, while the negative control treatment removed about 30% of the biofilm, treatment with undiluted Polypeptide Q resulted in almost 60% of the biofilm being removed (Figure 2).

When the diluted Polypeptide Q samples (10-fold dilution) were tested for biofilm removal, the results were more potent than those obtained with undiluted Polypeptide Q, presumably due to less inhibition from aggregation or oligomerization of the polypeptide at higher concentrations, and/or the effects of impurities that have an inhibitory effect at higher concentrations. In Figure 3, the initial amount of biofilm showed an absorbance of about 1.0 at 570 nm. By comparison, the negative control treatment resulted in an absorbance of about 0.7 at 570 nm, treatment with undiluted Polypeptide Q resulted in an absorbance measurement of about 0.4 at 570 nm, and treatment with diluted Polypeptide Q resulted in a further reduction of biofilm-specific staining, with an absorbance of about 0.15 at 570 nm. Measured in terms of percent biofilm removal, in Figure 4 the negative control treatment removed about 30% of the biofilm, and treatment with undiluted Polypeptide Q resulted in almost 60% of the biofilm being removed, while treatment with the diluted Polypeptide Q resulted in over 90% of the biofilm being removed.
