Identification of reaction product of GmF3G2″Gt-a (cultivar Nezumisaya). (A) Elution profiles of the standards (kaempferol 3-O-glucoside and kaempferol 3-O-sophoroside) and reaction product of GmF3G2″Gt-a protein. (B) UV spectra of the standard (kaempferol 3-O-sophoroside) and reaction product of GmF3G2″Gt-a protein. Mass spectra (C) and MS/MS spectra (D) of the standard (kaempferol 3-O-sophoroside) and reaction product of GmF3G2″Gt-a protein. E, The MS/MS fragmentation for kaempferol 3-O-sophoroside. K3Glc, kaempferol 3-O-glucoside; K3Glc2″Glc, kaempferol 3-O-sophoroside.
