ENZYME: 2.4.1.192

Entry

EC 2.4.1.192                Enzyme

Name

nuatigenin 3beta-glucosyltransferase;
uridine diphosphoglucose-nuatigenin glucosyltransferase

Class

Transferases;
Glycosyltransferases;
Hexosyltransferases

Sysname

UDP-glucose:(20S,22S,25S)-22,25-epoxyfurost-5-ene-3beta,26-diol 3-O-beta-D-glucosyltransferase

Reaction(IUBMB)

UDP-glucose + (20S,22S,25S)-22,25-epoxyfurost-5-ene-3beta,26-diol = UDP + (20S,22S,25S)-22,25-epoxyfurost-5-ene-3beta,26-diol 3-O-beta-D-glucoside [RN:R04577]

Reaction(KEGG)

R04577

Substrate

UDP-glucose [CPD:C00029];
(20S,22S,25S)-22,25-epoxyfurost-5-ene-3beta,26-diol [CPD:C04715]

Product

UDP [CPD:C00015];
(20S,22S,25S)-22,25-epoxyfurost-5-ene-3beta,26-diol 3-O-beta-D-glucoside [CPD:C04859]

Comment

Some other sapogenins can act as glucosyl acceptors. Involved in the biosynthesis of plant saponins. Not identical with EC 2.4.1.173 (sterol 3beta-glucosyltransferase) or EC 2.4.1.193 (sarsapogenin 3beta-glucosyltransferase).
