The protein release factor 2 (RF2) participates in Escherichia coli polypeptide chain termination with codon specificity (UAA or UGA). A colicin E1 recombinant identified in the Carbon and Clarke E. coli bank contains the protein release factor 2 gene. A 1.7-kilobase E. coli fragment has been subcloned into the plasmid pUC9 vector. Bacterial cells, containing the plasmid recombinant, produce elevated levels of protein release factor 2 as detected by an immune precipitation assay and in vitro measurement of UGA-directed peptide chain termination and [3H]UGA codon recognition.
