ID   1.3.1.77
DE   Anthocyanidin reductase.
AN   ANR.
CA   A flavan-3-ol + 2 NAD(P)(+) = an anthocyanidin + 2 NAD(P)H.
CC   -!- Forms 2,3-cis-flavan-3-ols.
CC   -!- The isomeric 2,3-trans-flavan-3-ols are formed from flavan-3,4-diols
CC       by EC 1.17.1.3.
CC   -!- While the enzyme from the legume Medicago truncatula (MtANR) uses
CC       both NADPH and NADH as reductant, that from the crucifer Arabidopsis
CC       thaliana (AtANR) uses only NADPH.
CC   -!- Also, while the substrate preference of MtANR is
CC       cyanidin>pelargonidin>delphinidin, the reverse preference is found
CC       with AtANR.
