General annotation (Comments)

Function

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. Beta-lysylation at Lys-34 is required for alleviation. The Pro codons and their context do not affect activity; only consecutive Pro residues (not another amino acid) are affected by EF-P. Has stimulatory effects on peptide bond formation between ribosome-bound initiator tRNA(fMet) and puromycin, and N-acetyl-Phe tRNA(Phe)-primed poly(U)-directed poly(Phe) synthesis. Ref.13 Ref.14

Pathway

Protein biosynthesis; polypeptide chain elongation. HAMAP-Rule MF_00141

Subunit structure

Binds 30S, 50S and 70S ribosomes, possibly near the A site, note that T.thermophilus structures show binding between the P and E sites (PDB 3HUW and 3HUY). Proportionally less EF-P binds to larger polysomes, suggesting it has a role early in translation. It is present in 1 copy per 10 ribosomes.

Subcellular location

Cytoplasm HAMAP-Rule MF_00141.

Post-translational modification

Is beta-lysylated on the epsilon-amino group of Lys-34 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 Lys-34 would allow additional potential stabilizing hydrogen-bond interactions with the P-tRNA (Ref.10 Ref.11 Ref.12 and Ref.15). HAMAP-Rule MF_00141

Disruption phenotype

Disruption of this gene leads to lethality (Ref.7) or to a very slow growth phenotype (Ref.15). Required for the expression of poly-Pro-containing proteins. Ref.7 Ref.13 Ref.15

Sequence similarities

Belongs to the elongation factor P family.

Caution

The modification on Lys-34 was initially thought to be a spermidine residue (Ref.9).

Mass spectrometry

Molecular mass is 20591.6 Da from positions 2 - 188. Determined by ESI. With N6-(3,6-diaminohexanoyl)-5-hydroxy-Lys-34. Ref.12
