Fig. 1: Growth of E. coli MG1655 deficient strains in the MA medium.

a Growth in the 96-well plate containing various concentrations of L-canavanine or b H-Lys-Ala-OH. After being cultured at 37 oC for 24 h, the growth was monitored by measuring the optical density at 600 nm (OD600nm). Data are from n = 3 independent experiments, Error bars represent SEM.
