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.
Catalytic activity	3-phenylpropanoic acid + NADH + O(2) = cis-3-(2-carboxyethyl)-3,5-cyclohexadiene-1,2-diol + NAD(+). Cinnamic acid + H(+) + NADH + O(2) = cis-3-(2-carboxyethenyl)-3,5-cyclohexadiene-1,2-diol + NAD(+).
Pathway	Aromatic compound metabolism; 3-phenylpropionic acid degradation.
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.
Sequence similarities	Belongs to the bacterial ring-hydroxylating dioxygenase beta subunit family.
