Figure 4From: Analysis of the function of E. coli 23S rRNA helix-loop 69 by mutagenesisCell-free Poly(U)-dependent protein synthesis activity in the presence of thiostrepton. Ratio of protein synthesis in the presence and absence of the drug is given as resistance. Standard deviations from 2–5 independent experiments are shown. Control plasmid is ptBsB1067T.Back to article page
