Krocetin glukoziltransferaza (EC 2.4.1.271, krocetin GTaza, UGTCs2) je enzim sa sistematskim imenom UDP-glukoza:krocetin 8-O-D-glukoziltransferaza.[1][2] Ovaj enzim katalizuje sledeću hemijsku reakciju
- (1) UDP-glukoza + krocetin UDP + beta-D-glukozil krocetin
- (2) UDP-glukoza + beta-D-glukozil krocetin UDP + bis(beta-D-glukozil) krocetin
- (3) UDP-glukoza + beta-D-gentiobiozil krocetin UDP + beta-D-gentiobiozil beta-D-glukozil krocetin
Kod Crocus sativus ovaj enzim esterifikuje slobodnu karboksilnu grupu krocetina ili krocetin glikozil estra.
