Predicted to enable aminocarboxymuconate-semialdehyde decarboxylase activity and zinc ion binding activity. Predicted to be involved in several processes, including aging; negative regulation of quinolinate biosynthetic process; and tryptophan catabolic process. Predicted to act upstream of or within quinolinate metabolic process. Predicted to be active in cytosol. Orthologous to human ACMSD (aminocarboxymuconate semialdehyde decarboxylase).
