2.7.2.8 ATP + N-acetyl-L-glutamate - 2.7.2.8 ATP + N-acetyl-L-glutamate key enzyme in regulation of arginine biosynthesis 2.7.2.8 ATP + N-acetyl-L-glutamate enzyme synthesis not repressed by exogenous L-arginine or its precursors 2.7.2.8 ATP + N-acetyl-L-glutamate second enzyme of arginine biosynthesis 2.7.2.8 ATP + N-acetyl-L-glutamate NAGK catalyzes the second step of arginine biosynthesis. In Pseudomonas aeruginosa, this step is rate limiting, and feedback regulated and sigmoidally inhibited by arginine 2.7.2.8 additional information NAGK strongly interacts with PII protein only in the presence of Mg-ATP, this process is reversed by 2-oxoglutarate 2.7.2.8 additional information NAGK interacts with PII protein
