Figure 5. DksA prevents loss of viability due to slow ribosome translocation.
(A) Plating efficiencies of rpsL[SmP] and rpsL[SmP] ΔdksA cells grown in the presence or absence of 50 μg/ml streptomycin. Error bar: standard deviation (n=4). (B) Plating efficiencies of ΔdksA cells carrying three different ribosomal mutations that alter translation accuracy. The rpsD12 mutant has increased translation errors and the rpsL[SmP] and rpsL141 mutations result in improved translational fidelity. Error bar: standard deviation (n=3).
