Glutamate synthase 1
WebCarbamoyl Phosphate Synthase 1, abbreviated as CPS1, is activated by its natural activator N-Acetyl glutamate, which in turn is synthesized from acetyl-CoA and glutamic acid in the reaction catalyzed by N-Acetyl glutamate synthase, commonly called NAGS. N-Acetyl Glutamate is required for the Urea cycle to take place. Web5.3.1 N-Acetylglutamate Synthase (NAGS) Deficiency. NAGS deficiency is the rarest of all the urea cycle defects. The enzyme is primarily expressed in the liver and intestine, and catalyzes the formation of NAG from glutamate and acetyl-CoA. NAG is the essential allosteric cofactor for CPS1, the first and rate-limiting enzyme of urea cycle.
