The annotation and conditions in this rule are derived from the following entries: P0A6N4 (EFP_ECOLI), Q76G20 (EFP_THET8), P64036 (EFP_SALTY)

If a protein meets these conditions... i

Common conditions

    • Matches HAMAP signature MF_00141
    • taxon = Bacteria
    • fragment ≠ the sequence is fragmented
    • Does not match HAMAP signature MF_00646

Special conditions

  • Involved in peptide bond synthesis. Alleviates ribosome stalling that occurs when 3 or more consecutive Pro residues or the sequence PPG is present in a protein, possibly by augmenting the peptidyl transferase activity of the ribosome. Modification of @RESIDUE_NAME_AT_POS|Lys|34|@i is required for alleviation.
  • Involved in peptide bond synthesis. Stimulates efficient translation and peptide-bond synthesis on native or reconstituted 70S ribosomes in vitro. Probably functions indirectly by altering the affinity of the ribosome for aminoacyl-tRNA, thus increasing their reactivity as acceptors for peptidyl transferase.

  • Is beta-lysylated on the epsilon-amino group of @RESIDUE_NAME_AT_POS|Lys|34|@i by the combined action of EpmA and EpmB, and then hydroxylated on the C5 position of the same residue by EpmC. Lysylation is critical for the stimulatory effect of EF-P on peptide-bond formation. The lysylation moiety would extend toward the peptidyltransferase center and stabilize the terminal 3-CCA end of the tRNA. The hydroxylation of the C5 position on @RESIDUE_NAME_AT_POS|Lys|34|@i would allow additional potential stabilizing hydrogen-bond interactions with the P-tRNA.
  • May be beta-lysylated on the epsilon-amino group of @RESIDUE_NAME_AT_POS|Lys|34|@i by the combined action of EpmA and EpmB, and then hydroxylated on the C5 position of the same residue by EpmC (if this protein is present). Lysylation is critical for the stimulatory effect of EF-P on peptide-bond formation. The lysylation moiety may extend toward the peptidyltransferase center and stabilize the terminal 3-CCA end of the tRNA.
