Other names:
2-enoyl-CoA hydratase 2
AtECH2
ECH2
MaoC
MFE-2
PhaJAc
D-3-hydroxyacyl-CoA hydro-lyase
D-specific 2-trans-enoyl-CoA hydratase
Systematic name:
(3R)-3-hydroxyacyl-CoA hydro-lyase

Reaction

Comments:

This enzyme catalyses a hydration step in peroxisomal β-oxidation. The human multifunctional enzyme type 2 (MFE-2) is a 79000 Da enzyme composed of three functional units: (3R)-hydroxyacyl-CoA dehydrogenase, 2-enoyl-CoA hydratase 2 and sterol carrier protein 2-like units [1]. The enzymes from Aeromonas caviae [4] and Arabidopsis thaliana [5] are monofunctional enzymes. 2-Enoyl-CoA hydratase 3 from Candida tropicalis is a part from multifunctional enzyme type 2 [3].
