Termination efficiencies (kcat/KM (M−1 s−1)) of the wt eRF1 and mutant eRF1s at different stop codons. Mutations (A) in the loop 59–68, (B) at positions 33 and 70, (C) at positions 32, 36 and 131, (D) at positions 55, 125 and 129 and (E) at position 71. The termination efficiency of the human wt eRF1 was considered 100%.
