Flavanone 7 O glucoside 2" O beta L rhamnosyltransferase

In enzymology, a flavanone 7-O-glucoside 2"-O-beta-L-rhamnosyltransferase (EC 2.4.1.236) is an enzyme that catalyzes the chemical reaction

UDP-L-rhamnose + a flavanone 7-O-glucoside ⇌ UDP + a flavanone 7-O-[beta-L-rhamnosyl-(1->2)-beta-D-glucoside]

Thus, the two substrates of this enzyme are UDP-L-rhamnose and flavanone 7-O-glucoside, whereas its two products are UDP and [[flavanone 7-O-[beta-L-rhamnosyl-(1->2)-beta-D-glucoside]]].

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-L-rhamnose:flavanone-7-O-glucoside 2-O-beta-L-rhamnosyltransferase. Other names in common use include UDP-rhamnose:flavanone-7-O-glucoside-2"-O-rhamnosyltransferase, and 1->2 UDP-rhamnosyltransferase.
