EC 2.4.1.192     
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).
