 53-116 8.96e-24

RF-1 domain; This domain is found in peptide chain release factors such as RF-1 and RF-2, and a number of smaller proteins of unknown function. This domain contains the peptidyl-tRNA hydrolase activity. The domain contains a highly conserved motif GGQ, where the glutamine is thought to coordinate the water that mediates the hydrolysis.

peptide chain release factor 2; In many but not all taxa, there is a conserved real translational frameshift at a TGA codon. RF-2 helps terminate translation at TGA codons and can therefore regulate its own production by readthrough when RF-2 is insufficient. There is a Pfam model called "RF-1" for the superfamily of RF-1, RF-2, mitochondrial, RF-H, etc. [Protein synthesis, Translation factors]

 69-115 3.35e-10

putative peptide chain release factor H; Members of this protein family are bacterial proteins homologous to peptide chain release factors 1 (RF-1, product of the prfA gene), and 2 (RF-2, product of the prfB gene). The member from Escherichia coli K-12, designated prfH, appears to be a pseudogene. This class I release factor is always found as the downstream gene of a two-gene operon.
