Effects of gene argA deletion on cell growth. a Growth curves of strain N1 (E. coli ΔargA) in M9 minimal medium supplemented with 5 g/L glucose (without yeast extract), -Arg means the absence of l-arginine. + Arg means the presence of l-arginine. b Growth curves of strain N1 and BW25113 in M9 minimal medium added with different concentrations of n-acetylglutamate (0 g/L, 1 g/L, 5 g/L, 10 g/L, 20 g/L). Error bars are the standard deviation for three independent experiments
