|Product Overview :
||Recombinant DNAK was overexpressed in E. coli and purified to apparent homogeneity by using conventional column chromatography techniques (132 aa, 14.6 kDa). Additional amino acid(Met) is attached at N- terminus.
||DnaK, originally identified for its DNA replication by bacteriophage l in E. coli is the bacterial hsp70 chaperone. This protein is involved in the folding and assembly of newly synthesized polypeptide chains and in preventing the aggregation of stress-denatured proteins. Dnak(residues 508-638) of the substrate binding domain is a-helical and appears to act as a lid covering the substrate binding cleft.
||Liquid. In 25 mM Tris-HCl buffer (pH 7.5) containing 100 mM NaCl, 1 mM DTT, 10% glycerol.
|Molecular Weight :
||14.6 kDa (132aa).
||> 95% by SDS – PAGE.
||1 mg/ml (determined by Bradford assay).
