>cd04470 S1_EF-P_repeat_1 S1_EF-P_repeat_1: Translation elongation factor P (EF-P), S1-like RNA-binding domain, repeat 1. EF-P stimulates the peptidyltransferase activity in the prokaryotic 70S ribosome. EF-P enhances the synthesis of certain dipeptides with N-formylmethionyl-tRNA and puromycine in vitro. EF-P binds to both the 30S and 50S ribosomal subunits. EF-P binds near the streptomycine binding site of the 16S rRNA in the 30S subunit. EF-P interacts with domains 2 and 5 of the 23S rRNA. The L16 ribosomal protein of the 50S or its N-terminal fragment are required for EF-P mediated peptide bond synthesis, whereas L11, L15, and L7/L12 are not required in this reaction, suggesting that EF-P may function at a different ribosomal site than most other translation factors. EF-P is essential for cell viability and is required for protein synthesis. EF-P is mainly present in bacteria. The EF-P homologs in archaea and eukaryotes are the initiation factors aIF5A and eIF5A, respectively. EF-P
