| Sysname |
UDP-L-rhamnose:flavonol-3-O-D-glucoside 6''-O-L-rhamnosyltransferase |
|---|
| Reaction(IUBMB) |
UDP-L-rhamnose + a flavonol 3-O-D-glucoside = UDP + a flavonol
3-O-[beta-L-rhamnosyl-(1->6)-beta-D-glucoside] [RN:R03880] |
|---|
| Reaction(KEGG) |
R03880 > R04900
 |
|---|
| Substrate |
UDP-L-rhamnose [CPD:C02199];
flavonol 3-O-D-glucoside [CPD:C03946] |
|---|
| Product |
UDP [CPD:C00015];
flavonol 3-O-[beta-L-rhamnosyl-(1->6)-beta-D-glucoside] |
|---|
| Comment |
Converts flavonol 3-O-glucosides to 3-O-rutinosides. Also acts, more
slowly, on rutin, quercetin 3-O-galactoside and flavonol
3-O-rhamnosides. |
