  • Method for producing polysaccharide
    Patent number: 9670514
    Abstract: The present invention aims to provide a method for producing a polysaccharide with high efficiency using a polysaccharide synthase. The present invention provides a method for producing a polysaccharide, including allowing polysaccharide synthase (B) to act on ribonucleoside diphosphate-monosaccharide (A) to produce a polysaccharide, wherein in 10 to 100% of the duration in which (B) acts on (A), the concentration of ribonucleoside diphosphate in a reaction solution is lower than 100 times an inhibitory concentration IC50 against polysaccharide synthase (B).
    Type: Grant

  • METHOD FOR PRODUCING POLYSACCHARIDE
    Publication number: 20140134679
    Abstract: The present invention aims to provide a method for producing a polysaccharide with high efficiency using a polysaccharide synthase. The present invention provides a method for producing a polysaccharide, including allowing polysaccharide synthase (B) to act on ribonucleoside diphosphate-monosaccharide (A) shown below to produce a polysaccharide, wherein in 10 to 100% of the duration in which (B) acts on (A), the concentration of ribonucleoside diphosphate in a reaction solution is lower than 100 times an inhibitory concentration IC50 described below against polysaccharide synthase (B). Inhibitory concentration IC50: a concentration of ribonucleoside diphosphate at which an enzyme activity of polysaccharide synthase (B) is reduced by half while under a condition where (B) has a concentration at which (B) acts on ribonucleoside diphosphate-monosaccharide (A), wherein ribonucleoside diphosphate-monosaccharide (A) is used as a substrate and ribonucleoside diphosphate is used as an inhibitor.
