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. Defects in OXCT1 are a cause of succinyl-CoA-3-ketoacid- CoA transferase deficiency (SCOTD). A disorder of ketone body metabolism, characterized by episodic ketoacidosis. Patients are usually asymptomatic between episodes. Belongs to the 3-oxoacid CoA-transferase family. Note: This description may include information from UniProtKB.
