From: Structure of the 30S translation initiation complex coupled to paused RNA polymerase and its potential for riboregulation

Fig. 1

A Cryo-EM map of the 30S IC on the ompD mRNA with IF1 and IF3. B View of the isolated cryo-EM density around the ompD mRNA and IF1/IF3 which are shown as ribbon models. C Views of the cryo-EM map of the 30S IC on the ompD mRNA with IF1, IF2 and fMet-tRNAfMet. The rotation symbol on the left indicates the view in respect to (A). D Close view of the cryo-EM density of the codon-anticodon pair between the ompD mRNA and the initiator tRNA. E View of the isolated cryo-EM density for IF1 and IF2. Inset: Molecular model for the N2 subdomain of IF2 with the contacting region of the 16S rRNA near ribosomal protein uS4. F Molecular model of the first two OB-domains of the ribosomal bS1 protein. The cryo-EM density is shown as a mesh around bS1.
