Elongation Factor P, Recombinant, E. coli, aa1-188, His-Tag (Efp)
Description
Purity ~90% (SDS-PAGE). 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 Lys-34 is required for alleviation. Source: Recombinant protein corresponding to aa1-188 from E. coli Elongation Factor P, fused to His-Tag at N-terminal, expressed in Yeast. Molecular Weight: ~22.6kD AA
