WebtRNAs act as peptidyl transferases catalyzing peptide bond formation between the amino acid at the P site and the newly recruited amino acid at the A site. There are 20 different … WebIn this scenario, the peptide transfer from the tRNA in the P site to the tRNA on the A site cannot be performed and the ribosomes are stalled with cognate, non-acylated tRNA on the A site. This is the molecular event sensed by RelA, which binds to the stalled ribosomes to catalyze the transfer of the β and γ phosphates from ATP to GTP or GDP ...
