Recombinant E.coli DnaK Chaperone Hsp70, Co-chaperone with DnaJ (1-384)

• Cat.No.: DnaK-314E
• Product Overview: The ATPase domain of recombinant DNAK was overexpressed in E. coli and purified to apparent homogeneity by using conventional column chromatography techniques (384 aa, 41.6 kDa).

Specification

• Cat. No.: DnaK-314
• Description: 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(amino acids1-384) is N-terminal ATPase domain and ATP bound to the ATPase domain induces a conformational change in the substrate binding domain(residues385-638). The protein coding region of the ATPase domain of DNAK (amino acids 1-384) was amplified by PCR and cloned into an E. coli expression vector.
