Comments
[?]
| FUNCTION | Catalyzes the cleavage of the C5-C6 bond of 2-hydroxy-6- oxononadienedioate and 2-hydroxy-6-oxononatrienedioate, a dienol ring fission product of the bacterial meta-cleavage pathway for degradation of phenylpropionic acid. |
| CATALYTIC ACTIVITY | Reaction=(2Z,4E)-2-hydroxy-6-oxonona-2,4-dienedioate + H2O = (2Z)-2- hydroxypenta-2,4-dienoate + succinate + H(+); Xref=Rhea:RHEA:34187, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30031, ChEBI:CHEBI:66887, ChEBI:CHEBI:67152; EC=3.7.1.14; |
| CATALYTIC ACTIVITY | Reaction=(2Z,4E,7E)-2-hydroxy-6-oxonona-2,4,7-trienedioate + H2O = (2Z)-2-hydroxypenta-2,4-dienoate + fumarate + H(+); Xref=Rhea:RHEA:34191, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:29806, ChEBI:CHEBI:66888, ChEBI:CHEBI:67152; EC=3.7.1.14; |
| PATHWAY | Aromatic compound metabolism; 3-phenylpropanoate degradation. |
| SUBUNIT | Homodimer. |
