Predicted to enable saccharopine dehydrogenase (NAD+, L-glutamate-forming) activity. Predicted to be involved in lysine biosynthetic process via aminoadipic acid. Predicted to act upstream of or within L-lysine catabolic process. Predicted to be located in mitochondrion. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in hyperlysinemia. Orthologous to human AASS (aminoadipate-semialdehyde synthase). [provided by Alliance of Genome Resources, Apr 2022]
