KEGG   ENZYME: 4.2.1.74
Entry
EC 4.2.1.74                 Enzyme                                 
Name
medium-chain-enoyl-CoA hydratase;
long-chain enoyl coenzyme A hydratase (incorrect);
long-chain-enoyl-CoA hydratase (incorrect);
long-chain-(3S)-3-hydroxyacyl-CoA hydro-lyase (incorrect)
Class
Lyases;
Carbon-oxygen lyases;
Hydro-lyases
Sysname
medium-chain-(3S)-3-hydroxyacyl-CoA hydro-lyase
Reaction(IUBMB)
a medium-chain (3S)-3-hydroxyacyl-CoA = a medium-chain trans-2-enoyl-CoA + H2O [RN:R02685]
Reaction(KEGG)
R02685 > R04170 R04738 R04740 R04744 R04746 R04749 R07889 R07893 R07897
Substrate
medium-chain (3S)-3-hydroxyacyl-CoA
Product
medium-chain trans-2-enoyl-CoA;
H2O [CPD:C00001]
Comment
Acts in the reverse direction. The best substrate for the porcine enzyme is oct-2-enoyl-CoA. Unlike EC 4.2.1.17 enoyl-CoA hydratase, it does not act on crotonoyl-CoA.
