Metabolism
Cyanidin 3-O-rutinoside 5-O-glucosyltransferase
In enzymology, a cyanidin 3-O-rutinoside 5-O-glucosyltransferase () is an enzyme that catalyzes the chemical reaction
:UDP-glucose + cyanidin 3-O-rutinoside \rightleftharpoons UDP + cyanidin 3-O-rutinoside 5-O-beta-D-glucoside
Thus, the two ...
uses UDP-glucose and cyanidin 3-O-rutinoside (antirrhinin) to produce UDP and
cyanidin 3-O-rutinoside 5-O-beta-D-glucoside.
