NAGS (N-acetylglutamate synthase)

Gene

• Entrez ID: 162417
• Gene name: N-acetylglutamate synthase
• Gene symbol: NAGS
• Synonyms (NCBI Gene): AGAS, ARGA
• Chromosome: 17
• Chromosome location: 17q21.31
• Summary: The N-acetylglutamate synthase gene encodes a mitochondrial enzyme that catalyzes the formation of N-acetylglutamate (NAG) from glutamate and acetyl coenzyme-A. NAG is a cofactor of carbamyl phosphate synthetase I (CPSI), the first enzyme of the urea cycl
