FIG. 3.

Growth curves of wild-type E. coli and mutant strains growing on MMA supplemented with 0.2% MurNAc (6.8 mM) and induced with 0.5 mM IPTG (solid symbols) or without induction (open symbols): wild-type E. coli (MC4100) carrying control plasmid pCS19 with (▾) and without induction (▿); murP (yfeV) deletion strain CM103 carrying plasmid pCS19 with (•) and without (○) induction; murP deletion strain CM103 carrying plasmid pCS19YfeV with (▪) and without (□) induction; and murP deletion strain CM103 carrying plasmid pCS19YfeV-His₆ with induction (▴). Representative data out of three replicates are shown.
