Definitions
- the object of the invention is the production of polyglucan and
- the recombinant amylosucrase described there shows the activity of the native amylosucrase.
- WO 95/31553 also describes the production of linear polysaccharides by means of biotransformation, the linear polysaccharide being obtained by catalytic reaction of monomeric building blocks such as oligomeric saccharides, e.g. is produced by mono- and / or disaccharides.
- poly (1,4-alpha-D-glucan) is synthesized in WO 95/31553 by means of a polysaccharide synthase, the alpha-1,4-glycosyltransferase or synonymously amylosucrase (EC 2.4.1.4).
- WO 95/31553 and PCT / EP 98/05573 also disclose nucleic acid sequences which lead to a protein with the activity of an amylosucrase in E. coli.
- the linear polymers obtained in this way have an application advantage over branched polymers with regard to processability or special properties, such as, for example, mechanical stability and durability.
- pharmaceutical (human and veterinary), medical (human and Veterinary area), cosmetic or agrochemical area Applications of great commercial importance in which properties or combinations of properties are required which are either not obtained by linear polymers or whose specific properties are for use in the abovementioned or other areas of application over that for the specific one Application go beyond what is necessary.
- the achievement of special properties is associated with higher manufacturing costs. If these properties are not required in the application, this procedure should be avoided.
- Properties that do not necessarily require the use of linear polymers can, for example, be improved in the formability of
- test specimens of special geometry the porosity of test specimens for the general release of active substances of any kind, in particular in the pharmaceutical and agro sector, the swellability, the easier chemical modification due to more accessible functional groups and others.
- the object of the invention is achieved in that recombinant
- Polyglucan sucrase is used in the presence of biogenic substances - preferably enzymes - and is used to produce polyglucan and polyglucan derivatives.
- Polyglucan sucrases as disclosed in PCT / EP 98/05573 are particularly preferred (cf. SEQ ID No. 1).
- the invention therefore relates to an amylosucrase with the amino acid sequence SEQ ID No. 1 or a redundant variant.
- polyglucan and polyglucan derivatives include in particular amylose and amylose derivatives.
- the surprisingly high product uniformity of the polyglucan and polyglucan derivatives obtained, in particular the molecular weights achieved, is advantageous.

- Preferred molecular weights are in the range from 5 x from 10 3 to 10 6 daltons, particularly preferably in the range from 5 x from 10 3 to 5 x from 10 4 daltons.
- the polyglucans and polyglucan derivatives according to the invention are also distinguished by a high variety, which are determined by the polydispersity of the polyglucans and polyglucan derivatives.
- the polydispersity can vary widely. Different polydispersities are of interest for different uses.
- the quotient of the mean polymer weight and the mean polymer number can vary from 1.0 to 100 or greater, with polydispersities in the range from 1.1 to 15 being preferred for special applications. Polyglucans or polyglucan derivatives which have polydispersities in the range from 1.1 to 5 are particularly advantageous.
- Biocompatible in the sense of this invention means that the polysaccharides used are subjected to complete biological degradation and that there is no harmful accumulation in the food chain, in particular in the human organism.
- Biodegradation refers to any process that takes place in vivo that leads to degradation or destruction of the polymer.
- hydrolytic or enzymatic processes also fall within this range.
- the nature-identical character of the polysaccharides used is of great importance.
- the polysaccharides in question are therefore also particularly suitable for therapeutic, diagnostic or prophylactic use.
- enzyme mixtures increased yields of polyglucan and polyglucan derivatives can be obtained by so-called enzyme mixtures.
- Advantageous enzymes are preferably considered without the following list being conclusive: transferases and glycosyltransferases
- Beta-1 3-galactosyl-O-glycosyl-glycoprotein beta-1, 6-N-acetylglucosaminyltransferase.

- the invention therefore relates to the inexpensive derivatization of polyglucan.
- the derivatization means that the
- Derivatives in the sense of these inventions are also those that undergo a reaction specifically on one of the C atoms C-2, C-3 or C-6, namely from> 0% to a maximum of 100%, or that mixtures occur, i.e. different percentage derivatizations at different positions in the C6 body of a glucan unit.
- a reaction specifically on one of the C atoms C-2, C-3 or C-6 namely from> 0% to a maximum of 100%, or that mixtures occur, i.e. different percentage derivatizations at different positions in the C6 body of a glucan unit.
- the hydroxyl group on the C-6 atom of the glucan base in the case of the hydroxyl group on the C-6 atom of the glucan base in
- Polyglucan can be obtained in particular advantageously degrees of branching from 1% to 40%. These polyglucan derivatives are particularly noteworthy by degrees of branching from 2% to 10%.
- the nature of the branches and the number of branches in the polyglucan derivatives described are distinguished by the fact that they can differ from those of the natural, that is to say naturally occurring, polyglucans, as can be obtained from plants, animals or other organisms .
- Another object of this invention is therefore also the modified production of polyglucan using biogenic substances.
- biogenic substances include biotic substances that are useful for or under the influence of biological organisms, especially in metabolic processes.
- Biogenic substances can also be those which preferably have the following elements: C, H, O, N, P, S, B, Si, Se, S, alkali metals, alkaline earth metals, halogens, Co, Fe, Hg,

- Reaction partners / parameters of the biotransformation are isolated and further changed in a further reaction. This can be done by adding other biogenic compounds, preferably enzymes.
- Polyglucans and / or polyglucan derivatives can be described as follows.
- the modification of the polyglucans or polyglucan derivatives can take place via whether only the course of the reaction of the biotransformation, that is to say the implementation of
- Sucrose and its derivatives to polyglucan and / or polyglucan derivatives should be changed (This can be done, for example, by consuming the Biotransformation happen fructose), or it can be formed by the reaction or reaction in the reaction of amylosucrase with biogenic substances directly a polyglucan and / or one or more polyglucan derivatives.
- One example is the changed course of the reaction which arises from the fact that phosphorylation and / or methylation and / or sulfation and / or further modifications result in an increased or decreased solubility of the polyglucan and in this way, for example, changed chain lengths or the like .
- further modifying enzymes e.g. be encoded in the same operon as the amylosucrase, and purified in parallel with this enzyme.
- a mixture of different biogenic substances preferably different enzymes including amylosucrase, is created during the production and separation of the amylosucrase, which can be used in a biocatalysis (biotransformation).
- polymer blends Such mixtures are also known to the person skilled in the art under the term “polymer blends”.
- modified amylosucrases could cause sugar, monosaccharides, disaccharides,
- Oligosaccharides can be better integrated into the polymer structure, in the sense of a faster reaction or in the sense of greater compatibility with other monomeric sugar units which are incorporated into the polymer backbone. But also a chain termination, which can lead to special functional molecules due to their special polymer end groups, the special one
- Polyglucans can be used as a starting material for further chemical modifications.
- Another object of the invention is the use of the polyglucans and / or polyglucan derivatives obtained according to the invention, as follows: Use as a pharmaceutical and / or agrochemical formulation for application in agriculture (such as tablets, capsule ingredients, suspensions, emulsions and others to those skilled in the art in the fields mentioned known formulations), active ingredient carrier and / or depot formulation, in particular tablet excipient, use as a food and / or food additive, use as a cosmetic additive.
