    Phenotypes of a mutant

  • essential [Pubmed|12682299]
  • The protein

    Catalyzed reaction/ biological activity

  • binds to the ribosome through specific recognition of messenger RNA stop codons and triggers hydrolysis of the bond between the nascent polypeptide and the transfer RNA at the peptidyl-tRNA site, thereby releasing the newly synthesized protein. PrfA is highly specific for a U in the first stop-codon position and recognizes UAA and UAG
  • Protein family

  • prokaryotic/mitochondrial release factor family (with [protein|12E06FD3A36D95AE82E3C65788FA98178039592F|PrfB], according to UniProt)
  • Structure

  • [PDB|1ZBT] (from ''Streptococcus mutans'', 58% identity)
