ENZYME: 1.3.1.77

Entry

EC 1.3.1.77                 Enzyme

Name

anthocyanidin reductase [(2R,3R)-flavan-3-ol-forming];
ANR (gene name) (ambiguous);
flavan-3-ol:NAD(P)+ oxidoreductase;
anthocyanidin reductase (ambiguous)

Class

Oxidoreductases;
Acting on the CH-CH group of donors;
With NAD+ or NADP+ as acceptor

Sysname

(2R,3R)-flavan-3-ol:NAD(P)+ 3,4-oxidoreductase

Reaction(IUBMB)

a (2R,3R)-flavan-3-ol + 2 NAD(P)+ = an anthocyanidin with a 3-hydroxy group + 2 NAD(P)H + H+ [RN:R07351 R07352]

Reaction(KEGG)

R07352 > R06541 R06542 R06543;
R07351

Substrate

(2R,3R)-flavan-3-ol [CPD:C22577];
NAD+ [CPD:C00003];
NADP+ [CPD:C00006]

Product

anthocyanidin with a 3-hydroxy group [CPD:C21381];
NADH [CPD:C00004];
NADPH [CPD:C00005];
H+ [CPD:C00080]

Comment

The enzyme participates in the flavonoid biosynthesis pathway found in plants. It catalyses the double reduction of anthocyanidins, producing (2R,3R)-flavan-3-ol monomers required for the formation of proanthocyanidins. While the enzyme from the legume Medicago truncatula (MtANR) can use 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. cf. EC 1.3.1.112, anthocyanidin reductase [(2S)-flavan-3-ol-forming].
