2-hydroxyhexa-2,4-dienoate hydratase

2-hydroxyhexa-2,4-dienoate hydratase (, tesE (gene), hsaE (gene)) is an enzyme with systematic name 4-hydroxy-2-oxohexanoate hydro-lyase ((2Z,4Z)-2-hydroxyhexa-2,4-dienoate-forming). This enzyme catalyses the following chemical reaction


 * 4-hydroxy-2-oxohexanoate $$\rightleftharpoons$$ (2Z,4Z)-2-hydroxyhexa-2,4-dienoate + H2O

This enzyme catalyses a late step in the bacterial steroid degradation pathway.
