| Method |
pre-steady-state kinetic experiments. Rate constants monitored by fluorescence changes in labeled tRNAs |
| Comments |
Constant is for coding recognition of (EF-Tu+ GTP+ aa-tRNA) ternary complex and A site of ribosome. This value is 1000 Fold faster for near cognate codons (that carry one nucleotide mismatch)tRNA than for cognate (with correct codons) tRNA. |
