Predicted glycosylation pathway of C-3 position of group A saponin Ab (A) and DDMP saponin βa (B) in soybean seed hypocotyls. The sugar chain positions of C-3 and C-22 are indicated in each chemical structure. GmSGT2 and GmSGT3 are glycosyltransferases reported by Shibuya et al. (2010). Sg-3 and Sg-4 control glycosylation of second and third sugar moieties.
