>TIGR00503 prfC peptide chain release factor 3; InterPro: IPR004548 Peptide chain release factor 3 increases the formation of ribosomal termination complexes and stimulates activity of RF-1 and RF-2. It binds to guanine nucleotides and has a strong preference for UGA stop codons. This translation releasing factor, RF-3 (prfC) was originally described as stop codon-independent, in contrast to peptide chain release factor 1 (RF-1, prfA) and RF-2 (prfB). RF-1 and RF-2 are closely related to each other, while RF-3 is similar to elongation factors EF-Tu and EF-G; RF-1 is active at UAA and UAG and RF-2 is active at UAA and UGA. All bacteria and organelles have RF-1. The Mycoplasmas and organelles, which translate UGA as Trp rather than as a stop codon, lack RF-2. RF-3, in contrast, seems to be rare among bacteria and is found so far only in Escherichia coli and some other gamma subdivision Proteobacteria, in Synechocystis sp. (strain PCC 6803), and in Staphylococcus aureus.; GO: 0005525 GTP binding, 0016149 translation release factor activity codon specific, 0006415 translational termination, 0005737 cytoplasm.
