ENZYME entry: EC 2.4.1.159

Accepted Name
flavonol-3-O-glucoside L-rhamnosyltransferase
Alternative Name(s)
uridine diphosphorhamnose-flavonol 3-O-glucoside rhamnosyltransferase
Reaction catalysed
a flavonol 3-O-beta-D-glucoside + UDP-beta-L-rhamnose = a flavonol 3-O-[alpha-L-rhamnosyl-(1->6)-beta-D-glucoside] + UDP + H(+)
Comment(s)
  • A configuration-inverting rhamnosyltransferase that converts flavonol 3-O-glucosides to 3-O-rutinosides.
  • Also acts, more slowly, on rutin, quercetin 3-O-galactoside and flavonol 3-O-rhamnosides.
