Generation of a RelA-stalled ribosome complex. (A) The bicistronic 2XermCL_S10K mRNA was translated in the presence of 10 μM erythromycin (ERY) in order to generate (B) ErmCL-S10K_SRC disomes. (C) ErmCL_S10K-SRC disomes were converted to monosomes by antisense DNA-mediated RNase H cleavage, as shown by sucrose density gradient centrifugation and negative stain electron microscopy (EM). (D) A-tRNA deficient ErmCL_S10K-SRCs were used as substrate for (E) RelA binding in the presence of deacylated tRNALys, GDP and α, β-methylene-ATP.
