Accepted name: cyanidin 3-O-rutinoside 5-O-glucosyltransferase

Reaction: UDP-α-D-glucose + cyanidin-3-O-rutinoside = UDP + cyanidin 3-O-rutinoside 5-O-β-D-glucoside

Glossary: cyanidin 3-O-rutinoside = cyanidin-3-O-α-L-rhamnosyl-(1→6)-β-D-glucoside
cyanidin = 3,3',4',5,7-pentahydroxyflavylium

Other name(s): uridine diphosphoglucose-cyanidin 3-rhamnosylglucoside 5-O-glucosyltransferase; cyanidin-3-rhamnosylglucoside 5-O-glucosyltransferase; UDP-glucose:cyanidin-3-O-D-rhamnosyl-1,6-D-glucoside 5-O-D-glucosyltransferase

Systematic name: UDP-α-D-glucose:cyanidin-3-O-α-L-rhamnosyl-(1→6)-β-D-glucoside 5-O-β-D-glucosyltransferase

Comments: Isolated from the plants Silene dioica (red campion) [1], Iris ensata (Japanese iris) [2] and Iris hollandica (Dutch iris) [3]. Also acts on the 3-O-rutinosides of pelargonidin, delphinidin and malvidin, but not the corresponding glucosides or 6-acylglucosides. The enzyme does not catalyse the glucosylation of the 5-hydroxy group of cyanidin 3-glucoside.
