In enzymology a 3-hydroxybutyryl-CoA epimerase (EC 5.1.2.3) is an enzyme that catalyzes the chemical reaction(S)-3-hydroxybutanoyl-CoA (R)-3-hydroxybutanoyl-CoAHence this enzyme has one substrate (S)-3-hydroxybutanoyl-CoA and one product (R)-3-hydroxybutanoyl-CoA.This enzyme belongs to the family of isomerases specifically those racemases and epimerases acting on hydroxy acids and derivatives. The systematic name of this enzyme class is 3-hydroxybutanoyl-CoA 3-epimerase.
