General annotation (Comments)

Function	Part of the multicomponent 3-phenylpropionate dioxygenase. Converts 3-phenylpropionic acid (PP) and cinnamic acid (CI) into 3-phenylpropionate-dihydrodiol (PP-dihydrodiol) and cinnamic acid-dihydrodiol (CI-dihydrodiol), respectively. Ref.5
Catalytic activity	3-phenylpropanoate + NADH + O₂ = 3-(cis-5,6-dihydroxycyclohexa-1,3-dien-1-yl)propanoate + NAD⁺. (2E)-3-phenylprop-2-enoate + NADH + O₂ = (2E)-3-(2,3-dihydroxyphenyl)prop-2-enoate + NAD⁺.
Cofactor	Binds 1 2Fe-2S cluster Probable. Binds 1 iron ion Probable.
Pathway	Aromatic compound metabolism; 3-phenylpropanoate degradation. HAMAP MF_01648
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 alpha subunit family. Contains 1 Rieske domain.
