WebRF1 and RF2 recognize the stop codon of the mRNA and facilitate hydrolysis of the peptidyl-tRNA ester bond, releasing the completed protein (reviewed in 1). Mutants isolated using E. coli strain SQ110 carried the mutation in the prfA gene, which resulted in the replacement of Asp241 of the encoded RF1 with a glycine residue ( Supplementary Fig. 2 ). WebThere is no single hydrolysis method that will effectively cleave all proteins to single amino acids completely and quantitatively. This is owing to the varying stability of the peptide …
