CC   -!- FUNCTION: Part of the multicomponent 3-phenylpropionate
CC       dioxygenase. Converts 3-phenylpropionic acid (PP) and cinnamic
CC       acid (CI) into 3-phenylpropionate-dihydrodiol (PP-dihydrodiol) and
CC       cinnamic acid-dihydrodiol (CI-dihydrodiol), respectively (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: 3-phenylpropanoic acid + NADH + O(2) = cis-3-
CC       (2-carboxyethyl)-3,5-cyclohexadiene-1,2-diol + NAD(+).
CC   -!- CATALYTIC ACTIVITY: Cinnamic acid + H(+) + NADH + O(2) = cis-3-(2-
CC       carboxyethenyl)-3,5-cyclohexadiene-1,2-diol + NAD(+).
CC   -!- PATHWAY: Aromatic compound metabolism; 3-phenylpropanoate
CC       degradation.
CC   -!- SUBUNIT: This dioxygenase system consists of four proteins: the
CC       two subunits of the hydroxylase component (hcaE and hcaF), a
CC       ferredoxin (hcaC) and a ferredoxin reductase (hcaD) (By
CC       similarity).
CC   -!- SIMILARITY: Belongs to the bacterial ring-hydroxylating
CC       dioxygenase beta subunit family.
