Summary
OXCT2 is a testis-specific succinyl-CoA:3-oxoacid CoA transferase (EC 2.8.3.5), which catalyzes the reversible transfer of CoA from succinyl-CoA to acetoacetate in the first step of ketone body utilization. See also OXCT1 (MIM 601424).[supplied by OMIM, Mar 2008]

Comments

Comment Type Description
Catalytic Activity Succinyl-CoA + a 3-oxo acid = succinate + a 3- oxoacyl-CoA.
Function Key enzyme for ketone body catabolism. Transfers the CoA moiety from succinate to acetoacetate. Formation of the enzyme-CoA intermediate proceeds via an unstable anhydride species formed between the carboxylate groups of the enzyme and substrate (By similarity).
Pathway Ketone metabolism; succinyl-CoA degradation; acetoacetyl- CoA from succinyl-CoA
Similarity Belongs to the 3-oxoacid CoA-transferase family.
Subcellular Location Mitochondrion .
Subunit Homodimer.
Tissue Specificity Testis specific.
