Sysname
UDP-alpha-D-glucuronate:soyasapogenol 3-O-D-glucuronosyltransferase (configuration-inverting)
Reaction(IUBMB)
UDP-alpha-D-glucuronate + soyasapogenol B = UDP + soyasapogenol B 3-O-beta-D-glucuronide [RN:R09636]
Reaction(KEGG)
Substrate
UDP-alpha-D-glucuronate [CPD:C00167];
soyasapogenol B [CPD:C08980]
Product
UDP [CPD:C00015];
soyasapogenol B 3-O-beta-D-glucuronide [CPD:C19763]
