(S)-3-Hydroxybutanoyl-CoA = (R)-3-hydroxybutanoyl-CoA
epimerization of D-3-hydroxyacyl-CoA does not occur directly but proceeds instead via 2-trans-enoyl-CoA as an intermediate by combined actions of a novel D-specific enoyl-CoA hydratase, D-hydratase, and an L-specific enoyl-CoA hydratase
-
(S)-3-Hydroxybutanoyl-CoA = (R)-3-hydroxybutanoyl-CoA
the multienzyme complex catalyzes the rapid and direct dehydration of D-3-hydroxy-4-trans-decenoyl-CoA to 2-trans,4-trans-decadienoyl-CoA, which is slowly hydated to L-3-hydroxy-4-trans-decenoyl-CoA
-
(S)-3-Hydroxybutanoyl-CoA = (R)-3-hydroxybutanoyl-CoA
epimerization in rat liver is not catalyzed by a single protein but probably occurs via two steps
-
(S)-3-Hydroxybutanoyl-CoA = (R)-3-hydroxybutanoyl-CoA
epimerization occurs solely by a dehydration/hydration mechanism
-
(S)-3-Hydroxybutanoyl-CoA = (R)-3-hydroxybutanoyl-CoA

both the enoyl-CoA hydratase activity, EC 4.2.1.17 and the 3-hydroxyacyl-CoA epimerase activity, EC 5.1.2.3 are eliminated by the site-directed mutation alpha/Gly116 to Phe. This provides direct evidence that both enzymes are associated with a common active site on the amino-terminal domain of the multifunctional enzyme complex which exhibits the activities of EC 4.2.1.17, EC 2.3.1.16, EC 5.1.2.3, EC 1.1.1.35, and EC 5.3.3.3
