CC   -!- FUNCTION: Part of the multicomponent 3-phenylpropionate dioxygenase,
CC       that converts 3-phenylpropionic acid (PP) and cinnamic acid (CI) into
CC       3-phenylpropionate-dihydrodiol (PP-dihydrodiol) and cinnamic acid-
CC       dihydrodiol (CI-dihydrodiol), respectively. {ECO:0000255|HAMAP-
CC       Rule:MF_01651}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+) + NAD(+) + 2 reduced [2Fe-2S]-[ferredoxin] = NADH + 2
CC         oxidized [2Fe-2S]-[ferredoxin]; Xref=Rhea:RHEA:16521, Rhea:RHEA-

CC         ChEBI:CHEBI:33737, ChEBI:CHEBI:33738, ChEBI:CHEBI:57540,
CC         ChEBI:CHEBI:57945; EC=1.18.1.3; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01651};
CC   -!- COFACTOR:
CC       Name=FAD; Xref=ChEBI:CHEBI:57692;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01651};
CC   -!- PATHWAY: Aromatic compound metabolism; 3-phenylpropanoate degradation.
CC       {ECO:0000255|HAMAP-Rule:MF_01651}.
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_01651}.
CC   -!- SIMILARITY: Belongs to the bacterial ring-hydroxylating dioxygenase
CC       ferredoxin reductase family. {ECO:0000255|HAMAP-Rule:MF_01651}.
