    • 产品描述:

      Recombinant E.coli UTI89 / UPEC dnaK?Protein is encoded by dnaK?gene — recombinant dnaK DNA — that has integrated foreign plasmids into the Yeast genome, the foreign DNA is replicated along with the host DNA. In addition, the expression of foreign proteins requires the use of specialized expression vectors and often necessitates the significant restructuring of the foreign coding sequence. The subsequent expression process includes small-scale expression, protein identification, large-scale expression, and protein purification. The purity of this recombinant dnaK is 90%+.

      DnaK is a protein coding gene that encodes Chaperone protein DnaK. According to some research, DnaK may have the following features.
      Stimulation of DnaK's ATPase activity may contribute to its more efficient recycling. ATP-bound DnaK is the predominant form that initiates interactions with substrates for chaperone activity. DnaK also has a prominent function in stabilizing proteins for subsequent folding by GroEL. The DnaK protein contributed to the growth of E. coli by not only protecting some enzymes from denaturation, but also reactivating some enzymes when they misfolded or aggregated. Substrate shuttling between the DnaK and GroEL systems suggests a chaperone network that promotes protein folding.
