Enoyl-CoA hydratase EchA19

UniProtKB accession:  O53561

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Degradation of the cholesterol side chain involves 3 multistep beta-oxidation cycles, this may be involved in the second cycle (Probable). Hydrates 3-OCDO-CoA ((22E)-3-oxo-chol-4,22-dien-24-oyl-CoA) to make (22R)-HOCO-CoA (3-oxo-chol-4-ene-(22R)-hydroxy-24-oyl-CoA). Also acts on octenoyl-CoA. Not active on (E)-3-OCDS-CoA ((E)-3-oxocholest-4,24-dien-26-oyl-CoA) or 3-OPDC-CoA (3-oxo-4,17-pregnadiene-20-carboxyl-CoA). Hydrates the same substrate as ChsH3, but the 2 enzymes make different stereoisomers of the product (PubMed:32649175, PubMed:33826843).
