Description

Predicted to enable acetyltransferase activity and lipoic acid binding activity. Acts upstream of or within branched-chain amino acid metabolic process. Predicted to be active in mitochondrion. Is expressed in brain; gut; intestine; liver; and muscle. Used to study maple syrup urine disease. Human ortholog(s) of this gene implicated in maple syrup urine disease. Orthologous to human DBT (dihydrolipoamide branched chain transacylase E2).
