Lead time: 22-32 working days

Research Topic: Microbiology

Uniprot ID: B1XDQ0

Gene Names: efp

Organism: Escherichia coli (strain K12 / DH10B)


Expression Region: 1-188aa

Sequence Info: Full Length

Source: Yeast

Tag Info: N-terminal 6xHis-tagged

MW: 22.6 kDa

Alternative Name(s): Short name:EF-P

Relevance: 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.

III, Burland V., Mau B., Petrosino J.F., Qin X., Muzny D.M., Ayele M., Gibbs R.A., Csorgo B., Posfai G., Weinstock G.M., Blattner F.R.J. Bacteriol. 190:2597-2606(2008)

Purity: Greater than 90% as determined by SDS-PAGE.

Storage Buffer: Tris-based buffer,50% glycerol

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
