ENZYME entry: EC 1.3.1.77
| Accepted Name |
|---|
| Anthocyanidin reductase.
|
| Alternative Name(s) |
|---|
| ANR. |
| Reaction catalysed |
|---|
| A flavan-3-ol + 2 NAD(P)(+) <=> an anthocyanidin + 2 NAD(P)H |
| Comment(s) |
|---|
- Forms 2,3-cis-flavan-3-ols.
- The isomeric 2,3-trans-flavan-3-ols are formed from flavan-3,4-diols
by EC 1.17.1.3.
- While the enzyme from the legume Medicago truncatula (MtANR) uses
both NADPH and NADH as reductant, that from the crucifer Arabidopsis
thaliana (AtANR) uses only NADPH.
- Also, while the substrate preference of MtANR is
cyanidin>pelargonidin>delphinidin, the reverse preference is found
with AtANR.
