KEGG   ENZYME: 4.2.1.74Help
Entry
EC 4.2.1.74                 Enzyme                                 

Name
long-chain-enoyl-CoA hydratase;
long-chain enoyl coenzyme A hydratase
Class
Lyases;
Carbon-oxygen lyases;
Hydro-lyases
BRITE hierarchy
Sysname
long-chain-(3S)-3-hydroxyacyl-CoA hydro-lyase
Reaction(IUBMB)
a long-chain (3S)-3-hydroxyacyl-CoA = a long-chain trans-2-enoyl-CoA + H2O [RN:R02685]
Reaction(KEGG)
Substrate
long-chain (3S)-3-hydroxyacyl-CoA
Product
long-chain trans-2-enoyl-CoA;
H2O [CPD:C00001]
Comment
Acts in the reverse direction. The best substrate is oct-3-enoyl-CoA. Unlike EC 4.2.1.17 enoyl-CoA hydratase, it does not act on crotonoyl-CoA.
