ENZYME entry: EC 4.2.1.157

Accepted Name
(R)-2-hydroxyisocaproyl-CoA dehydratase
Alternative Name(s)
2-hydroxyisocaproyl-CoA dehydratase
Reaction catalysed
(R)-2-hydroxy-4-methylpentanoyl-CoA <=> 4-methylpent-2-enoyl-CoA + H2O
Comment(s)
  • The enzyme, isolated from the bacterium Peptoclostridium difficile, is involved in the reductive branch of L-leucine fermentation.
  • It catalyzes an alpha/beta-dehydration, which depends on the reductive formation of ketyl radicals on the substrate generated by injection of a single electron from the ATP-dependent activator protein HadI.
