Background: Recombinant proteins overexpressed in E. coli are usually deposited in inclusion bodies. Cysteines in the protein contribute to this process. Inter- and intra- molecular disulfide bonds in chitinase, a cysteine-rich protein, cause aggregation when the recombinant protein is overexpressed in E. coli. Hence, aggregated proteins should be solubilized and allowed to refold to obtain nat...
Mechanical unfolding and refolding of ubiquitin are studied by Monte Carlo simulations of a Gō model with binary variables. The exponential dependence of the time constants on the force is verified, and folding and unfolding lengths are computed, with good agreement with experimental results. Furthermore, the model exhibits intermediate kinetic states, as observed in experiments. Unfolding and ...
We have developed a facile means for the refolding of milligram quantities of purified proteins that employs gel filtration chromatography. We demonstrate by electrophoretic mobility shift and NMR spectroscopy that human ETS-1 protein, bovine ribonuclease A and E. coli integration host factor can be refolded into the native conformation using this technique. We have extended this strategy to th...
The kinetics of the refolding of the enzyme, human carbonic anhydrase II (HCA II), at different temperatures, together with the Escherichia coli chaperonin GroEL, has been studied. The Arrhenius plots for the spontaneous, GroEL-assisted, and GroEL/ES-assisted refolding of HCA II show that the apparent activation energy (E(a)) is lower in the presence of the chaperonin GroEL alone than for the s...
