    摘要: The present invention relates to trehalose phosphorylases which are useful for the industrial production of trehalose-analogues and glycosyl phosphates. More specifically, the invention discloses trehalose phosphorylases which are mutated in specific amino acid regions. These specific mutations result in modified substrate specificities of the enzymes. In addition, the present invention discloses a wild type trehalose phosphorylase from the marine organism Caldanaerobacter subterraneus, and mutated types thereof, which are highly thermostable and have a broad acceptor and donor specificity.

    摘要: An in vitro method to produce a glycoside is described which includes the steps of contacting the cellodextrin phosphorylase from Clostridium stercorarium with alpha-glucose-1-phosphate or alpha-galactose-1-phosphate and an acceptor, and glycosylating the acceptor. The acceptor may be an alkyl beta-glucoside, an aryl beta-glucoside, a glucolipid, an alkyl beta-sophoroside, an aryl beta-sophoroside or a sophorolipid. Alkylcellobiosides, arylcellobiosides, cellobiolipids, cellotriolipids, glucosophorolipids and cellobiosesophorolipids are produced when alpha-glucose-1-phosphate is used as donor. Corresponding lactosides are produced when alpha-galactose-1-phosphate is used as donor.

    摘要: The present invention relates to the biocatalytic production of glycosides. In particular, the invention discloses a method to produce alkylcellobiosides, arylcellobiosides, cellobiolipids, cellotriolipids, glucosophorolipids and cellobiosesophorolipids via the usage of a cellodextrin phosphorylase (CDP) derived from Clostridium stercorarium (CsCDP). The method of the present invention is feasible for use in industrial glycosylation processes and has advantageous properties compared to classical as chemical glycosylation reactions. Moreover, said method can also be employed to produce corresponding lactosides such a lactolipids when a-galactose-1-phosphate instead of a-glucose-1-phosphate is used as a donor.

    摘要: The present invention relates to yeast species which are normally capable of producing sophorolipids but which are modified in such way that they are incapable producing the latter compounds. These sophorolipid-negative strains surprisingly display equal growth characteristics and biomass formation as their wild type counterparts and are hence useful for the production of compounds such as recombinant proteins, glycolipids, polyhydroxyalkanoates and carotenoides. In addition, the present invention discloses two glucosyltransferase genes with key-functions in sophorolipid production.
