In enzymology, an anthocyanidin reductase (EC 1.3.1.77) is an enzyme that catalyzes the chemical reaction

a flavan-3-ol + 2 NAD(P)+ an anthocyanidin + 2 NAD(P)H + H+

The 3 substrates of this enzyme are flavan-3-ol, NAD+, and NADP+, whereas its 4 products are anthocyanidin, NADH, NADPH, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is flavan-3-ol:NAD(P)+ oxidoreductase. Other names in common use include AtANR, and MtANR. This enzyme participates in flavonoid biosynthesis.

Flavan-3-ols are a subgroup of flavonoids. They are derivatives of flavans that possess a 2-phenyl-3,4-dihydro-2H-chromen-3-ol skeleton. Flavan-3-ols are structurally diverse and include a range of compounds, such as catechin, epicatechin gallate, epigallocatechin, epigallocatechin gallate, proanthocyanidins, theaflavins, thearubigins. They play a part in plant defense and are present in the majority of plants.

This nomenclature is the inverse of that which is commonly used in flavonoids, where the hydroxy-group is assumed absent if it is not specified, e. g. flavan-3-ol, flavan-4-ol, flavan-3,4-ol and flavonol.
