Protein attributes

Sequence length	400 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

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. HAMAP MF_01651
Catalytic activity	Reduced ferredoxin + NAD+ = oxidized ferredoxin + NADH. HAMAP MF_01651
Cofactor	FAD.
Pathway	Aromatic compound metabolism; 3-phenylpropanoate degradation. HAMAP 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).
Sequence similarities	Belongs to the bacterial ring-hydroxylating dioxygenase ferredoxin reductase family.
