CC   -!- FUNCTION: Part of the multicomponent 3-phenylpropionate dioxygenase.
CC       Converts 3-phenylpropionic acid (PP) and cinnamic acid (CI) into 3-
CC       phenylpropionate-dihydrodiol (PP-dihydrodiol) and cinnamic acid-
CC       dihydrodiol (CI-dihydrodiol), respectively. {ECO:0000255|HAMAP-
CC       Rule:MF_01649}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=3-phenylpropanoate + H(+) + NADH + O2 = 3-(cis-5,6-
CC         dihydroxycyclohexa-1,3-dien-1-yl)propanoate + NAD(+);

CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(E)-cinnamate + H(+) + NADH + O2 = (2E)-3-(cis-5,6-
CC         dihydroxycyclohexa-1,3-dien-1-yl)prop-2-enoate + NAD(+);

CC         Rule:MF_01649};
CC   -!- PATHWAY: Aromatic compound metabolism; 3-phenylpropanoate degradation.
CC       {ECO:0000255|HAMAP-Rule:MF_01649}.
CC   -!- SUBUNIT: This dioxygenase system consists of four proteins: the two
CC       subunits of the hydroxylase component (HcaE and HcaF), a ferredoxin
CC       (HcaC) and a ferredoxin reductase (HcaD). {ECO:0000255|HAMAP-
CC       Rule:MF_01649}.
CC   -!- SIMILARITY: Belongs to the bacterial ring-hydroxylating dioxygenase
CC       beta subunit family. {ECO:0000255|HAMAP-Rule:MF_01649}.
