Structural, kinetic and thermodynamic characterizations of SDS-induced molten globule state of a highly negatively charged cytochrome c.

abstract：:Pure recA protein was easily obtained from Escherichia coli harboring plasmid pTM-2 which carried the recA gene by two chromatographic steps on phosphocellulose and DEAE-cellulose. RecA protein was stable in the pH range of 6 to 9 at 25 degrees C. RecA protein was found to aggregate highly under these conditions. Lowe...
