Recombinant Escherichia coli Elongation factor 4(lepA)

Product Type Recombinant Protein
Uniprot No. B1IVQ8
Species Escherichia coli (strain ATCC 8739 / DSM 1576 / Crooks)
Gene Names lepA
Protein Names Recommended name: Elongation factor 4 Short name= EF-4 EC= 3.6.5.n1 Alternative name(s): Ribosomal back-translocase LepA
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°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Function Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre-translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP-dependent manner.
Subcellular Location Cell inner membrane, Peripheral membrane protein, Cytoplasmic side
Protein Families TRAFAC class translation factor GTPase superfamily, Classic translation factor GTPase family, LepA subfamily
