Other name(s): enoyl hydrase; unsaturated acyl-CoA hydratase; β-hydroxyacyl-CoA dehydrase; β-hydroxyacid dehydrase; acyl coenzyme A hydrase; crotonase; crotonyl hydrase; 2-octenoyl coenzyme A hydrase; enoyl coenzyme A hydratase; 2-enoyl-CoA hydratase; short-chain enoyl-CoA hydratase; ECH; trans-2-enoyl-CoA hydratase; short-chain enoyl-CoA hydratase; enoyl coenzyme A hydrase (D); enoyl coenzyme A hydrase (L); short chain enoyl coenzyme A hydratase; D-3-hydroxyacyl-CoA dehydratase

Systematic name: (3S)-3-hydroxyacyl-CoA hydro-lyase

Comments: Acts in the reverse direction. With cis-compounds, yields (3R)-3-hydroxyacyl-CoA. cf. EC long-chain-enoyl-CoA hydratase.
