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).
CATALYTIC ACTIVITY: 3-phenylpropanoic acid + NADH + O₂ = cis-3-(2-carboxyethyl)-3,5-cyclohexadiene-1,2-diol + NAD⁺.
CATALYTIC ACTIVITY: Cinnamic acid + H⁺ + NADH + O₂ = cis-3-(2-carboxyethenyl)-3,5-cyclohexadiene-1,2-diol + NAD⁺.
COFACTOR: Binds 1 iron ion (By similarity).
COFACTOR: Binds 1 2Fe-2S cluster per subunit (By similarity).
PATHWAY: Aromatic compound metabolism; 3-phenylpropionic acid degradation .
SUBUNIT: 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).
SIMILARITY: Belongs to the bacterial ring-hydroxylating dioxygenase alpha subunit family.
SIMILARITY: Contains 1 Rieske domain.
