2.4.1.193 |
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 2.4.1.173 (sterol 3β-glucosyltransferase) or EC 2.4.1.192 (nuatigenin 3β-glucosyltransferase). |
