Protein existence	Inferred from homology

General annotation (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 By similarity. HAMAP-Rule MF_01654
Catalytic activity	(2Z,4E)-2-hydroxy-6-oxonona-2,4-diene-1,9-dioate + H2O = (2Z)-2-hydroxypenta-2,4-dienoate + succinate. HAMAP-Rule MF_01654 (2Z,4E,7E)-2-hydroxy-6-oxonona-2,4,7-triene-1,9-dioate + H2O = (2Z)-2-hydroxypenta-2,4-dienoate + fumarate. HAMAP-Rule MF_01654
Pathway	Aromatic compound metabolism; 3-phenylpropanoate degradation. HAMAP-Rule MF_01654
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the MhpC alpha/beta hydrolase family.
Sequence caution	The sequence CAR16469.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
