2-hydroxy-6-oxonona-2,4-dienedioate hydrolase

2-hydroxy-6-oxonona-2,4-dienedioate hydrolase is an enzyme with systematic name -2-hydroxy-6-oxona-2,4-dienedioate succinylhydrolase. This enzyme catalyses the following chemical reaction:

-2-hydroxy-6-oxonona-2,4-diene-1,9-dioate + H₂O -2-hydroxypenta-2,4-dienoate + succinate
-2-hydroxy-6-oxonona-2,4,7-triene-1,9-dioate + H₂O -2-hydroxypenta-2,4-dienoate + fumarate

This enzyme catalyses a step in a pathway of phenylpropanoid compounds degradation.
