Crystal structure of human 3-oxoacid CoA transferase 1

Disease

[SCOT_HUMAN] Defects in OXCT1 are a cause of succinyl-CoA-3-ketoacid-CoA transferase deficiency (SCOTD) [MIM:245050]. A disorder of ketone body metabolism, characterized by episodic ketoacidosis. Patients are usually asymptomatic between episodes.[1][2][3]

Function

[SCOT_HUMAN] 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.

About this Structure

3dlx is a 4 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
