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+. HAMAP-Rule MF_01648

(2E)-3-phenylprop-2-enoate + NADH + O2 = (2E)-3-(2,3-dihydroxyphenyl)prop-2-enoate + NAD+. HAMAP-Rule MF_01648

Cofactor

Binds 1 2Fe-2S cluster Probable.

Binds 1 iron ion Probable.

Pathway

Aromatic compound metabolism; 3-phenylpropanoate degradation. HAMAP-Rule 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.
