Succinyl-CoA:3-ketoacid-coenzyme A transferase 1, mitochondrial is an enzyme that in humans is encoded by the OXCT1 gene.^[1][2] It is also known as succinyl-CoA-3-oxaloacid CoA transferase (SCOT). Mutations in this gene are associated with succinyl-CoA:3-oxoacid CoA transferase deficiency.^[3]

This gene encodes a member of the 3-oxoacid CoA-transferase gene family. The encoded protein is a homodimeric mitochondrial matrix enzyme that plays a central role in extrahepatic ketone body catabolism by catalyzing the reversible transfer of coenzyme A from succinyl-CoA to acetoacetate.^[2]
