Predicted to enable [acyl-carrier-protein] S-malonyltransferase activity. Predicted to be involved in fatty acid biosynthetic process. Predicted to act upstream of or within fatty acid metabolic process. Predicted to be active in mitochondrion. Human ortholog(s) of this gene implicated in optic atrophy. Orthologous to human MCAT (malonyl-CoA-acyl carrier protein transacylase).
