Protein attributes

Sequence length	400 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Part of the multicomponent 3-phenylpropionate dioxygenase, that converts 3-phenylpropionic acid (PP) and cinnamic acid (CI) into 3-phenylpropionate-dihydrodiol (PP-dihydrodiol) and cinnamic acid-dihydrodiol (CI-dihydrodiol), respectively By similarity. HAMAP-Rule MF_01651
Catalytic activity	Reduced ferredoxin + NAD+ = oxidized ferredoxin + NADH. HAMAP-Rule MF_01651
Cofactor	FAD By similarity.
Pathway	Aromatic compound metabolism; 3-phenylpropanoate degradation. HAMAP-Rule MF_01651
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 ferredoxin reductase family.
