Influence of the analogs of the tRNA acceptor end on the stability of the termination complexes. (A) Structure of the mini-helix obtained from tRNAVal(CG). (B) Toe-prints with eRF1, eRF1(AGQ) and eRF3c+GTP and mini-helix obtained from tRNAVal(CG) at UAA stop codon. (C) Toe-prints with eRF1, eRF1(AGQ) and eRF3c + GTP and cycloheximide at UAA stop codon. cDNAs corresponding to preTC and TC have the 127 and 125 nt length, respectively. RFU, relative fluorescence unit. The experiments have been replicated at least three times.
