| Accepted name: |
2-hydroxyhexa-2,4-dienoate hydratase |
| Reaction: |
4-hydroxy-2-oxohexanoate = (2Z,4Z)-2-hydroxyhexa-2,4-dienoate + H2O |
| Other name(s): |
tesE (gene name); hsaE (gene name) |
| Systematic name: |
4-hydroxy-2-oxohexanoate hydro-lyase [(2Z,4Z)-2-hydroxyhexa-2,4-dienoate-forming] |
| Comments: |
This enzyme catalyses a late step in the bacterial steroid degradation pathway. The product, 4-hydroxy-2-oxohexanoate, forms a 2-hydroxy-4-hex-2-enolactone under acidic conditions. |
