N-Acetylglutamate kinase (NAGK) catalyses the second step in the route of arginine biosynthesis. In many organisms this enzyme is inhibited by the final product of the route, arginine, and thus plays(More)
Carbamate kinase (CK) makes ATP from ADP and carbamoyl phosphate (CP) in the final step of the microbial fermentative catabolism of arginine, agmatine, and oxalurate/allantoin. Two previously(More)
N-Acetyl-L-glutamate kinase (NAGK), the structural paradigm of the enzymes of the amino acid kinase family, catalyzes the phosphorylation of the gamma-COO(-) group of N-acetyl-L-glutamate (NAG) by(More)
We test, using site-directed mutagenesis, predictions based on the X-ray structure of N-acetyl-L-glutamate kinase (NAGK), the paradigm of the amino acid kinase protein family, about the roles of(More)
Carbamoyl phosphate (CP), an essential precursor of arginine and the pyrimidine bases, is synthesized by CP synthetase (CPS) in three steps. The last step, the phosphorylation of carbamate, is also(More)
MuB is an ATP-dependent DNA-binding protein that regulates the activity of MuA transposase and delivers the target DNA for transposition of phage Mu. Mechanistic insight into MuB function is limited(More)
