(R)-2-hydroxyisocaproyl-CoA dehydratase.
based on mapping to UniProt Q5U923
(R)-2-hydroxy-4-methylpentanoyl-CoA = 4-methylpent-2-enoyl-CoA + H(2)O.
-!- 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.
