General Information

General Information Comment Organism
physiological function enzyme is responsible for conjugating the terminal (third) glucose at the C-3 sugar chain of soyasaponins. A double mutant lacking UGT91H9 and UGT91H4 fails to accumulate soyasaponins Ac and betag, and also soyasaponins Ab and alphag, i.e. the third Glc and Rha conjugations are both disabled Glycine max
