Codon binding by Inline graphic27 and the Inline graphic27;f5C34. The equilibrium binding of the two ASLs to the cognate and noncognate codons, AUG and AUA respectively, was assessed using programmed E. coli ribosomes. (The ASL unmodified and the wobble position is designated ‘Ψ27’; ASL modified at the wobble position is designated as ‘Ψ27;f5C34’.) The ASLs were bound to the A-site with E. coli Inline graphic bound to its cognate codon in the P-site. The ASLs were bound to the P-site with the Inline graphic bound to its cognate codon in the A-site.
