3.2.1.140 | In vitro refolding, overview. Denatured C-terminally His-tagged enzyme LnbX is refolded in the presence and absence of LnbY and metals Ca2and Mg2+. Purified LnbX is denatured in 6 M guanidine HCl. It is diluted 100fold by adding 50 mM HEPES buffer, pH 7.0, containing various concentrations of LnbY and metal ions 0.0-5.0 mM in a total volume of 0.5 ml, followed by immediate dialysis against HEPES buffer containing or not containing metal ions |
