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 (0.23 sec^-1) is 1000 Fold slower for cognate (with correct codons) tRNA than for non cognate (that carry one nucleotide mismatch codons) tRNA (80 sec^-1) |
