2-hydroxy-6-oxonona-2,4-dienedioate hydrolase ( EC 3.7.1.14, mhpC (gene)) is an enzyme with systematic name (2Z,4E)-2-hydroxy-6-oxona-2,4-dienedioate succinylhydrolase. [1] [2] [3] [4] [5] [6] This enzyme catalyses the following chemical reaction:
- (2Z,4E)-2-hydroxy-6-oxonona-2,4-diene-1,9-dioate + H2O (2Z)-2-hydroxypenta-2,4-dienoate + succinate
- (2Z,4E,7E)-2-hydroxy-6-oxonona-2,4,7-triene-1,9-dioate + H2O (2Z)-2-hydroxypenta-2,4-dienoate + fumarate
This enzyme catalyses a step in a pathway of phenylpropanoid compounds degradation.
