SUGCT

Coenzyme A (CoA) transferase that reversibly catalyzes the transfer of a CoA moiety from a dicarboxyl-CoA to a dicarboxylate in a metabolite recycling process. Displays preference for succinyl-CoA and glutarate-CoA as dicarboxyl-CoA donors and glutarate, succinate, adipate/hexanedioate, itaconate and 3-hydroxy-3-methylglutarate as dicarboxylate acceptors. Acts on intermediates or end products of lysine and tryptophan degradation pathway, in particular catalyzes succinyl-CoA-dependent reesterification of free glutarate into glutaryl-CoA to prevent renal excretion of glutarate. Upon inflammation, may convert macrophage-derived itaconate to itaconyl-CoA in erythroid precursors where it negatively regulates the TCA cycle and heme synthesis to limit erythroid differentiation in the context of stress erythropoiesis..
