Accepted name: |
nuatigenin 3β-glucosyltransferase |
Reaction: |
UDP-glucose + (20S,22S,25S)-22,25-epoxyfurost-5-ene-3β,26-diol = UDP + (20S,22S,25S)-22,25-epoxyfurost-5-ene-3β,26-diol 3-O-β-D-glucoside |
Other name(s): |
uridine diphosphoglucose-nuatigenin glucosyltransferase |
Systematic name: |
UDP-glucose:(20S,22S,25S)-22,25-epoxyfurost-5-ene-3β,26-diol 3-O-β-D-glucosyltransferase |
Comments: |
Some other sapogenins can act as glucosyl acceptors. Involved in the biosynthesis of plant saponins. Not identical with EC 2.4.1.173 (sterol 3β-glucosyltransferase) or EC 2.4.1.193 (sarsapogenin 3β-glucosyltransferase). |
