Accepted name: sarsapogenin 3β-glucosyltransferase
Reaction: UDP-glucose + (25S)-5β-spirostan-3β-ol = UDP + (25S)-5β-spirostan-3β-ol 3-O-β-D-glucoside
Other name(s): uridine diphosphoglucose-sarsapogenin glucosyltransferase
Systematic name: UDP-glucose:(25S)-5β-spirostan-3β-ol 3-O-β-D-glucosyltransferase
Comments: Specific to 5β-spirostanols. Involved in the biosynthesis of plant saponins. Not identical with EC (sterol 3β-glucosyltransferase) or EC (nuatigenin 3β-glucosyltransferase).
