N-Acetyltransferase 8 (NAT8), also known as aspartate acetyltransferase, is a human enzyme encoded by the *NAT8* gene located on chromosome 2 (2p13.3). It belongs to the N-acetyltransferase superfamily, which catalyzes the transfer of acetyl groups from acetyl-CoA to various substrates. NAT8 is primarily expressed in the kidney, brain, and liver, suggesting roles in organ-specific metabolic pathways. Structurally, it contains a conserved N-acetyltransferase domain critical for enzymatic activity.
NAT8 is implicated in acetylating amino acids like L-aspartate to generate N-acetyl-L-aspartate (NAA), a brain-abundant metabolite involved in myelin synthesis, neuronal osmoregulation, and energy metabolism. Dysregulation of NAT8 or NAA levels has been linked to neurological disorders such as Canavan disease and Alzheimer’s. In the kidney, NAT8 may regulate urinary acid excretion and electrolyte balance.
Recombinant human NAT8 protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) for functional studies, inhibitor screening, and structural analysis. Its recombinant form enables research into its catalytic mechanisms, substrate specificity, and potential therapeutic targeting in diseases like renal tubular acidosis or cancers with altered NAT8 expression. Recent studies also explore its role in cellular detoxification and drug metabolism, expanding its biomedical relevance.
