2-kumarat O-beta-glyukoziltransferaza
Enzimologiyada 2-kumarat O-beta-glyukoziltransferaza (EC)) — kimyoviy reaksiyani katalizlovchi ferment hisoblanadi.
- UDP-glyukoza + trans-2-gidroksisinnamat UDP + trans-beta-D-glyukosil-2-gidroksisinnamat
Shunday qilib, bu fermentning ikkita substrati UDP-glyukoza va trans-2-gidroksisinnamat, uning ikkita oxirgimahsuloti UDP va trans-beta-D-glyukosil-2-gidroksisinnamat hisoblanadi .
Bu ferment glikoziltransferazalar oilasiga, xususan, geksosiltransferazalarga tegishli boʻlib, shbu ferment sinfining sistematik nomi UDP-glyukoza:trans-2-gidroksisinnamat O-beta-D-glyukoziltransferazasi hisoblanadi. Umumiy qoʻllaniladigan boshqa nomlar orasida uridin difosfoglyukoza-o-kumarat glyukosiltransferaza va UDPG: o-kumar kislotasi O-glyukoziltransferaza kabilar mavjud. Bu ferment fenilpropanoid biosintezida ishtirok etadi.
