General annotation (Comments)

Function

Part of the multicomponent 3-phenylpropionate dioxygenase. Converts 3-phenylpropionic acid (PP) and cinnamic acid (CI) into 3-phenylpropionate-dihydrodiol (PP-dihydrodiol) and cinnamic acid-dihydrodiol (CI-dihydrodiol), respectively By similarity. HAMAP MF_01648

Catalytic activity

3-phenylpropanoic acid + NADH + O2 = cis-3-(2-carboxyethyl)-3,5-cyclohexadiene-1,2-diol + NAD+. HAMAP MF_01648

Cinnamic acid + H+ + NADH + O2 = cis-3-(2-carboxyethenyl)-3,5-cyclohexadiene-1,2-diol + NAD+. HAMAP MF_01648

Cofactor

Binds 1 iron ion By similarity. HAMAP MF_01648

Binds 1 2Fe-2S cluster per subunit By similarity. HAMAP MF_01648

Pathway

Aromatic compound metabolism; 3-phenylpropanoate degradation. HAMAP MF_01648

Subunit structure

This dioxygenase system consists of four proteins: the two subunits of the hydroxylase component (hcaE and hcaF), a ferredoxin (hcaC) and a ferredoxin reductase (hcaD) By similarity. HAMAP MF_01648

Sequence similarities

Belongs to the bacterial ring-hydroxylating dioxygenase alpha subunit family.

Contains 1 Rieske domain.
