EC 4.2.1.150     
Accepted name: short-chain-enoyl-CoA hydratase
Reaction: a short-chain (3S)-3-hydroxyacyl-CoA = a short-chain trans-2-enoyl-CoA + H2O
Other name(s): 3-hydroxybutyryl-CoA dehydratase; crotonase; crt (gene name)
Systematic name: short-chain-(3S)-3-hydroxyacyl-CoA hydro-lyase
Comments: The enzyme from the bacterium Clostridium acetobutylicum is part of the central fermentation pathway and plays a key role in the production of both acids and solvents. It is specific for short, C4-C6, chain length substrates and exhibits an extremely high turnover number for crotonyl-CoA. cf. EC 4.2.1.17, enoyl-CoA hydratase and EC 4.2.1.74, long-chain-enoyl-CoA hydratase.
