Flavanone 7-O-glucoside 2"-O-beta-L-rhamnosyltransferase () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are the flavanone glucoside, prunin, and UDP-rhamnose. Its products are naringin and uridine diphosphate (UDP).
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. Other flavanone 7-O-glucosides can be substrates, including those from hesperetin or based on the flavones luteolin and apigenin.
