Protein

Alpha-aminoadipic semialdehyde synthase, mitochondrial

Gene

AASS

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Bifunctional enzyme that catalyzes the first two steps in lysine degradation. The N-terminal and the C-terminal contain lysine-ketoglutarate reductase and saccharopine dehydrogenase activity, respectively.

Catalytic activityi

N(6)-(L-1,3-dicarboxypropyl)-L-lysine + NADP+ + H2O = L-lysine + 2-oxoglutarate + NADPH.
N(6)-(L-1,3-dicarboxypropyl)-L-lysine + NAD+ + H2O = L-glutamate + (S)-2-amino-6-oxohexanoate + NADH.

Involvement in diseasei

Hyperlysinemia, 1 (HYPLYS1) [MIM:238700]: An autosomal recessive metabolic condition with variable clinical features. Some patients present with non-specific seizures, hypotonia, or mildly delayed psychomotor development, and increased serum lysine and pipecolic acid on laboratory analysis. However, about half of the probands are reported to be asymptomatic, and hyperlysinemia is generally considered to be a benign metabolic variant.1 Publication
Note: The disease is caused by mutations affecting the gene represented in this entry.
