Ribosome A-site binding activity of native L. casei tRNAVal. GUU, GUC, GUA, GUG, and CCA (proline codon) are codons at the A site of the ribosomes. Aminoacylated native L. casei tRNAVal loaded with 14C-Val using ValRS bound not only to mRNA with GUA or GUG at the A site, but also to mRNA with GUU or GUC. Error bars are SEM for three independent experiments.
