FIG 4.

Spx toxicity is alleviated by deletion of ctsR or ywlE. (A) Growth curves of spx^cond, spx^cond ΔclpX, and spx^cond ΔclpP (genotypes as for Fig. 2B) in absence and presence of 100 µM IPTG. (B) WT, ΔmcsB, ΔywlE, and ΔmcsB ΔywlE cells in a spx^cond ΔclpX genetic background were surveyed on plates with or without 100 µM IPTG. The results are representative of two independent replicates.
