A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

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
UDP-beta-L-rhamnose + a flavonol 3-O-beta-D-glucoside <=> UDP + a flavonol 3-O-(alpha-L-rhamnosyl-(1->6)-beta-D-glucoside)
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.
