A26V
site-directed mutagenesis, the mutation deregulates the feedback inhibition of the enzyme
D162E
about 0.1% of wild-type activity
DELTA2-15
Km (N-acetyl-L-glutamate) increased compared to wild-type, kcat decreased compared to wild-type, IC50 (L-arginine) 71fold increased compared to wild-type
DELTA2-19
Km (N-acetyl-L-glutamate) increased compared to wild-type, kcat decreased compared to wild-type, IC50 (L-arginine) 148fold increased compared to wild-type
DELTA2-29
Km (N-acetyl-L-glutamate) increased compared to wild-type, kcat decreased compared to wild-type, IC50 (L-arginine) 163fold increased compared to wild-type
DELTA25
Km (N-acetyl-L-glutamate) highly increased compared to wild-type, kcat highly decreased compared to wild-type, IC50 (L-arginine) 17fold increased compared to wild-type
DELTA357-513
truncated mutant lacking C-terminal 150 amino acids (spanning residues 38-356), belonging to the DUF619 domain family, shows that is it stabilizes yNAGK, slows catalysis and modulates feed-back inhibition by arginine. Truncated yNAGK shows doubled kcat compared to wild-type, Km is almost not affected. IC50 (L-arginine) is lowered compared to wild-type. Truncated mutand shows lower thermal stability compared to wild-type
DELTA8
Km (N-acetyl-L-glutamate) increased compared to wild-type, kcat highly decreased compared to wild-type, IC50 (L-arginine) 16fold increased compared to wild-type
E17A
site-directed mutagenesis, the mutant shows reduced Vmax, the mutation results in decreased affinity of NAGK for arginine
E17D
site-directed mutagenesis, the mutant shows reduced Vmax, the mutation results in decreased affinity of NAGK for arginine
