Figure 1.
Secondary structure of the bacterial ribosomal A site with the antibiotic-resistant A1408m1A modification and chemical structure of 1-methyladenosine (m1A). The rRNA residues are numbered according to the numbering used in Escherichia coli 16S rRNA. The A/m1A1408, A1492 and A1493 residues are colored in orange, blue and red, respectively.
