DE RecName: Full=Peptide chain release factor 1 {ECO:0000255|HAMAP-Rule:MF_00093}; DE Short=RF-1 {ECO:0000255|HAMAP-Rule:MF_00093}; GN Name=prfA {ECO:0000255|HAMAP-Rule:MF_00093}; OrderedLocusNames=bbp_161; OS Buchnera aphidicola subsp. Baizongia pistaciae (strain Bp). OC Bacteria; Pseudomonadota; Gammaproteobacteria; Enterobacterales; OC Erwiniaceae; Buchnera. OX NCBI_TaxID=224915; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=Bp; RX PubMed=12522265; DOI=10.1073/pnas.0235981100; RA van Ham R.C.H.J., Kamerbeek J., Palacios C., Rausell C., Abascal F., RA Bastolla U., Fernandez J.M., Jimenez L., Postigo M., Silva F.J., RA Tamames J., Viguera E., Latorre A., Valencia A., Moran F., Moya A.; RT "Reductive genome evolution in Buchnera aphidicola."; RL Proc. Natl. Acad. Sci. U.S.A. 100:581-586(2003). CC -!- FUNCTION: Peptide chain release factor 1 directs the termination of CC translation in response to the peptide chain termination codons UAG and CC UAA. {ECO:0000255|HAMAP-Rule:MF_00093}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00093}. CC -!- PTM: Methylated by PrmC. Methylation increases the termination CC efficiency of RF1. {ECO:0000255|HAMAP-Rule:MF_00093}. CC -!- SIMILARITY: Belongs to the prokaryotic/mitochondrial release factor CC family. {ECO:0000255|HAMAP-Rule:MF_00093}.
