Description

Olive alcohol synthetase variants and engineered microorganisms expressing same
Technical Field
The present invention relates to the field of microorganisms and enzymes, in particular to olivetol synthase (OLS) variants and engineered microorganisms expressing the same for the production of Olivetol (OL) and Olivetolic Acid (OA).
Background
Cannabinoids are derived from the plant cannabis sativa (Cannabinoids)Cannabis sativa) The number of chemical molecules in the molecule exceeds 150. The currently used cannabinoids are mostly Cannabidiol (CBD), Tetrahydrocannabinol (THC) and Cannabigerol (CBG). CBD is one of the main chemical components in the plant cannabis, and is a non-addictive component of cannabinoids. THC is the major psychoactive substance in cannabis, can be addictive and is a substance that is strictly regulated in various countries throughout the world. CBG is generally classified as a micro-cannabinoid or a rare cannabinoid because of its low content in the plant cannabis sativa, and is known as the "parent" to cannabinoids because it is a common precursor to other cannabinoids. With the growth of cannabis, most of CBG is converted into CBD and THC, only a trace amount of CBG remains in the plant body, and the supply is severely limited, so that the development of CBG application is greatly limited.
Oligol and olivetol are type III polyketides derived from Cannabis (Cannabis) plants, have antibacterial, antitumor and anti-UV activities, and are key biosynthetic precursors of cannabinoids. There are few reports of natural extraction of olivetol and olivetol from plants. Moreover, plant cultivation is limited by factors such as the difficulty in obtaining high purity products compared to biosynthesis, strict plant control, limited productivity, the need for high plant cultivation and downstream extraction input, and low production stability. The chemical synthesis of the olive alcohol and the olive alcohol acid has high cost, and has the problems of environmental pollution, harsh conditions and the like. As far as the inventor knows, the biosynthesis of the olive alcohol and the olive alcohol acid by taking the Escherichia coli as the Chassis bacteria is not enough to meet the industrialization requirement. Tan Z et al (Tan Z, Clomburg J M, Gonzalez R. Synthetic pathway for the production of an oleatic acid in Escherichia coli [ J ]. ACS Synthetic biology, 2018, 7(8): 1886-. In 2020, patent No. WO2020176547A1 reported that by screening for an olive alcohol synthase derived from Cymbidium hybrid multivar, the yield of olive alcohol was found to be 40.7 mg/L.
There remains a need in the art for novel microorganisms for the biosynthesis of olive alcohol and olive alcohol acid in high yields.
Disclosure of Invention
The present invention meets the above-described need in the art by providing olive alcohol synthase (OLS) variants that biosynthesize olive alcohol and olive alcohol acid in high yields.

The present invention is based, at least in part, on the discovery that: host microorganisms expressing an olivine synthase (OLS) and/or an Olivine Acid Cyclase (OAC) can produce high concentrations of olivine and/or olivine acid by deleting the genomic fabH coding sequence in the host microorganism (e.g., escherichia coli). Without wishing to be bound by theory, it is believed that the deletion of the fabH gene promotes synthesis of olivine and/or olivine acid by the olive alcohol synthase (OLS) and/or Olive Acid Cyclase (OAC) in the engineered microorganism using intracellular increased levels of Malonyl-CoA (Malonyl-CoA) and Hexanoyl-CoA (Hexanoyl-CoA) as substrates. In this way, the engineered microorganism can be used to produce olivetol or olivetol on demand, thereby surpassing the cumbersome and costly prior art that still relies on complex synthetic chemistry.
Accordingly, in one aspect, the present invention provides an engineered microorganism, wherein the engineered microorganism is modified to express an olivine synthase (OLS), wherein the engineered microorganism has a deletion of the genomic fabH gene.
In some embodiments, the microorganism engineered to biosynthesize olivetol and olivetol is escherichia coli (e.

Conservative substitutions may be polar para-polar amino acids (glycine (G, Gly), serine (S, Ser), threonine (T, Thr), tyrosine (Y, Tyr), cysteine (C, Cys), asparagine (N, Asn), and glutamine (Q, Gln)); nonpolar versus nonpolar amino acids (alanine (a, Ala), valine (V, Val), tryptophan (W, Trp), leucine (L, Leu), proline (P, Pro), methionine (m, Met), phenylalanine (F, Phe)); acidic versus acidic amino acids (aspartic acid (D, Asp), glutamic acid (E, Glu)); basic pair basic amino acids (arginine (R, Arg), histidine (H, His), lysine (K, Lys)); charged amino acids (aspartic acid (D, Asp), glutamic acid (E, Glu), histidine (H, His), lysine (K, Lys) and arginine (R, Arg)); and hydrophobic versus hydrophobic amino acids (alanine (a, Ala), leucine (ULeu), isoleucine (I, Ile), valine (V, Val), proline (P, Pro), phenylalanine (F, Phe), tryptophan (W, Trp), and methionine (M, Met)). In some other embodiments, the mutant or variant may also comprise non-conservative substitutions.
In some embodiments, a mutant or variant polypeptide can have substitutions, additions, insertions, or deletions of amino acids in a range of about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100 or more or any two of the foregoing. A mutant or variant may have an activity of at least 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% or a range of any two of the foregoing values as compared to an unaltered enzyme. Enzyme activity can be determined by conventional techniques known in the art, such as colorimetric enzymatic assays.
As is well known to those skilled in the art, expression of a heterologous nucleic acid in a host can be improved (i.e., codon optimized) by replacing one or more encoding nucleotides (i.e., codons) in a nucleotide sequence encoding a polypeptide, such as an enzyme, with another codon for better expression in the host. One reason for this effect is because different organisms show a preference for different codons. In some embodiments, a nucleotide sequence encoding a polypeptide, such as an enzyme, disclosed herein is modified or optimized such that the resulting nucleotide sequence reflects codon bias for a particular host. For example, in some embodiments, the nucleotide sequence encoding a polypeptide, such as an enzyme, is modified or optimized for e.

A polynucleotide or polypeptide has a certain "sequence identity" or percentage of "identity" to another polynucleotide or polypeptide, meaning that when two sequences are aligned, the percentage of bases or amino acids are the same and in the same relative position. Determining the percent identity of two amino acid sequences or two nucleotide sequences can include aligning and comparing the amino acid residues or nucleotides at corresponding positions in the two sequences. A sequence is considered 100% identical if all positions in both sequences are occupied by the same amino acid residue or nucleotide. Sequence identity can be determined in a number of different ways, for example, sequences can be aligned using various methods and computer programs (e.g., BLAST, T-COFFEE, MUSCLE, MAFFT, etc.).
Some embodiments of the invention relate to expression constructs, e.g. vectors, such as plasmids, preferably expression constructs comprising one or more nucleotide sequences encoding OLS and/or OAC. The nucleotide sequence encoding OLS or OAC is as described above. Preferably, the expression construct is a plasmid. Preferably, the expression construct may be used to express OLS and/or OAC, more preferably to co-express both OLS and OAC, in escherichia coli, preferably in escherichia coli BW 25113.
Some embodiments of the invention relate to expression constructs, e.g., vectors, such as plasmids, comprising a nucleotide sequence encoding fadD. The nucleotide sequence encoding fadD is as described above. Preferably, the expression construct is a plasmid. Preferably, the expression construct can be used for the expression of fadD in e.coli, preferably e.coli BW 25113. In some embodiments, the host microorganism expresses fadD itself, and thus an expression construct encoding fadD is introduced into the host microorganism to overexpress fadD.
Engineering a microorganism may comprise expressing an enzyme of interest in the microorganism. In some embodiments, the expression constructs described herein are introduced into a host microorganism by transformation to express an enzyme of interest. The transformation can be carried out by methods well known in the art. For example, plasmids described herein comprising a nucleotide sequence encoding fadD can be introduced into e.coli by transformation to overexpress fadD. Transformation can be, but is not limited to, Agrobacterium-mediated transformation, electroporation with plasmid DNA, DNA uptake, biolistic transformation, virus-mediated transformation, or protoplast transformation. Transformation may be any other transformation method suitable for the particular host.
Expression of the enzyme of interest in the host microorganism to achieve the desired aim may be achieved as described above by converting the expression construct encoding the enzyme into the host microorganism, by integrating the expression construct encoding the enzyme into the genomic sequence of the host microorganism in a variety of ways, or by enhancing transcription and/or expression of enzyme encoding genes, such as fadD encoding genes, native to the host microorganism in a variety of ways, for example by using stronger regulatory elements such as promoters. Such means are generally well known to those skilled in the art. In some embodiments, the plasmids used herein are set forth in SEQ ID NO 7. In some embodiments, the plasmids used herein are set forth in SEQ ID NO 10. In some embodiments, the plasmids used herein are set forth in SEQ ID NO 11.
Engineering a microorganism may comprise intervening in the function of the protein of interest in said microorganism, e.g. reducing or eliminating the expression of said protein, which may be achieved, for example, by deleting genomic sequences of interest in said microorganism. In some embodiments, the genomic fabH gene in a microorganism described herein is deleted such that 3-oxoacyl- [ acyl carrier protein ] synthetase 3 (3-oxoacyl- [ acyl carrier protein ] synthase 3) is not expressed in the microorganism. In some embodiments, the amino acid sequence of 3-oxoacyl- [ acyl carrier protein ] synthetase 3 is shown as NCBI ACCESSION NO: NP-415609 (https:// www.ncbi.nlm.nih.gov/protein/16129054). In some embodiments, a genomic fadE gene in a microorganism described herein is deleted such that an acyl-CoA dehydrogenase (acyl-CoA dehydrogenase) is not expressed in the microorganism. In some embodiments, the amino acid sequence of the acyl-CoA dehydrogenase is shown as NCBI ACCESSION NO: NP-414756 (https:// www.ncbi.nlm.nih.gov/protein/90111100). In some embodiments, both genomic fabH and fadE genes in a microorganism described herein are deleted such that both 3-oxoacyl- [ acyl carrier protein ] synthetase 3 and acyl-CoA dehydrogenase are not expressed in the microorganism. In some embodiments, the fabH gene sequence that is deleted is shown in SEQ ID NO. 3, or is a variant sequence of SEQ ID NO. 3 that is deleted such that a protein having the same or similar function as 3-oxoacyl- [ acyl carrier protein ] synthetase 3 is not expressed. In some embodiments, the deleted fadE gene sequence is as shown in SEQ ID NO 6, or a variant sequence of SEQ ID NO 6 that is deleted such that a protein having the same or similar function as the acyl-CoA dehydrogenase is not expressed.
Deletion of genomic sequences of interest in a microorganism can be performed by methods known in the art. The genomic sequence may be deleted, for example, by designing an artificial sequence for lambda-Red homologous recombination against the genomic sequence, which is integrated into the genome at the target location using lambda-Red homologous recombination. Specific experimental protocols can be found in the examples described herein. In some embodiments, the artificial sequence for deletion of the fabH gene is shown in SEQ ID NO 1. In some embodiments, the portion of the genomic sequence of E.coli in which the fabH gene is deleted, such as BW25113, that is upstream and downstream of the original fabH gene site is SEQ ID NO 2. In some embodiments, the artificial sequence for deletion of the fadE gene is set forth in SEQ ID NO 4. In some embodiments, the portion of the genomic sequence of E.coli in which the fadE gene is deleted, e.g., BW25113, that is upstream and downstream of the original fadE gene site is SEQ ID NO 5.
In addition to deleting the genomic sequence of interest in the microorganism, the function of the protein of interest can be interfered with by other methods known in the art, including, but not limited to, interfering with transcription of the genomic sequence encoding the protein of interest, interfering with expression of mRNA encoding the protein of interest, interfering with delivery of the protein of interest, e.g., to the outside of the cell; more specifically, including, but not limited to, methods of deleting all or part of the genomic sequence encoding the protein of interest or its regulatory elements such as a promoter, inserting one or more nucleotides, e.g., a stop codon, that affects its transcription or mutating one or more nucleotides thereof to such an extent that the genomic sequence cannot be normally transcribed, in the middle of the genomic sequence encoding the protein of interest or its regulatory elements such as a promoter, introducing an agent that interferes with or silences mRNA encoding the protein of interest, e.g., an siRNA or dsRNAi agent, or a method of inhibiting or stopping the function of delivering the protein of interest, e.g., to an extracellular system (e.g., chaperones, signal sequences, transporters).
Suitable media for culturing the host may include standard media (e.g., Luria-Bertani broth, optionally supplemented with one or more other agents, such as an inducer; standard yeast media; and the like). In some embodiments, the medium can be supplemented with fermentable sugars (e.g., hexoses, such as glucose, xylose, and the like). In some embodiments, a suitable medium comprises an inducer. In certain such embodiments, the inducing agent comprises rhamnose.
The carbon source in a suitable medium for host culture may vary from simple sugars such as glucose to more complex hydrolysates of other biomass such as yeast extract. The addition of salts typically provides the necessary elements, such as magnesium, nitrogen, phosphorus, and sulfur, to allow the cell to synthesize polypeptides and nucleic acids. Suitable media may also be supplemented with selective agents, such as antibiotics, to select for maintenance of certain plasmids and the like. For example, if the microorganism is resistant to an antibiotic, such as ampicillin, tetracycline or kanamycin, the antibiotic can be added to the culture medium to prevent growth of cells that lack resistance. Suitable media may be supplemented with other compounds as necessary to select for desired physiological or biochemical properties, such as particular amino acids, and the like.

Synthetic pathway for the production of aliphatic acid in Escherichia coli [ J ]. ACS Synthetic biology, 2018, 7(8): 1886. 1896.), with a yield of 80 mg/L. In addition, the CZ-OL was tested to have an OL yield of 116.02mg/L, which is higher than that reported in the prior art patent No. WO2020176547A1, which found an olive alcohol synthase derived from Cymbium hybride multivar to have an olive alcohol yield of 40.7 mg/L.

Example 7: performance testing of OLS variant-containing strains
To further test whether the effect of the OLS variants on OA production was limited to that of a particular engineered strain, the effect of the OLS variants was tested in two non-engineered escherichia coli strains BW25113 and BL 21.
The p15A-Prha-OLS (WT) -OAC plasmid and the four p15A-Prha-OLS (mutant) -OAC plasmids were transformed into these two E.coli strains, respectively, to obtain strains BW (WT), BW (I52L), BW (S56A), BW (H262M), BW (K263R), BL21 (WT), BL21 (I52L), BL21 (S56A), BL21 (H262M), BL21 (K263R). The strain was tested for OA production as described in example 6.

Note: "-" indicates that OA was not detected
It can be seen that the above-described OLS variants achieve improved OA production in both wild-type and engineered strains. It was concluded that the OA production-improving effect of the OLS variant is not limited to a specific strain.
In addition, the corresponding version of the strain used herein for OA production without OAC expression (i.e., producing OL instead of OA) also obtained beneficial OL yields relative to the corresponding version of the OA production control strain herein without OAC expression (i.e., producing OL instead of OA).
While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention.
