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. |
| CATALYTIC ACTIVITY | Reaction=3-phenylpropanoate + NADH + O2 + H(+) = 3-(cis-5,6- dihydroxycyclohexa-1,3-dien-1-yl)propanoate + NAD(+); Xref=Rhea:RHEA:20357, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:51057, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:60087; EC=1.14.12.19; |
| CATALYTIC ACTIVITY | Reaction=(E)-cinnamate + NADH + O2 + H(+) = (2E)-3-(cis-5,6- dihydroxycyclohexa-1,3-dien-1-yl)prop-2-enoate + NAD(+); Xref=Rhea:RHEA:25058, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:15669, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:61451; EC=1.14.12.19; |
| COFACTOR | Name=Fe cation; Xref=ChEBI:CHEBI:24875; Note=Binds 1 Fe cation.; |
| COFACTOR | Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135; Note=Binds 1 [2Fe-2S] cluster per subunit. |
| PATHWAY | Aromatic compound metabolism; 3-phenylpropanoate degradation. |
| SUBUNIT | 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). |
| SIMILARITY | Belongs to the bacterial ring-hydroxylating dioxygenase alpha subunit family. |
