The production of correctly folded protein in Escherichia coli is often challenging because of aggregation of the overexpressed protein into inclusion bodies. Although a number of general and protein-specific techniques are available, their effectiveness varies widely. We report a novel method for enhancing the solubility of overexpressed proteins. Presence of a dipeptide, glycylglycine, in the...
Demonstration of TPNH Oxidase-The rate of decrease in light absorption at 340 rnp, due to TPNH, was used as an assay for the enzyme. The test was run routinely in glycylglycine buffer of pH 7.4. The conditions are given in detail in the legend to Fig. 1. Under these circumstances, the rate of change in optical density was roughly proportional to the amount of enzyme employed, in the range A log...
A new platinum derivative of the form H[Pt(IV)(Hdigly)Cl(2)(OH)(2)] (Hdigly==glycylglycine) damaged the Candida albicans cell membrane and inhibited the growth of the cells. The cytotoxic activity of H[Pt(IV)(Hdigly)Cl(2)(OH)(2)] on mammalian cells was 10-fold lower than that of cis-diammine-dichloroplatinum (cisplatin). Substitution of platinum for peptides is effective for enhancement of anti...
A novel heteronuclear 3d-4f compound having formula NdCu3L3·13H2O (where H3L = Schiff base derived from 5-bromosalicylaldehyde and glycylglycine and L 3– = C11H8N2O4Br) was obtained. It was characterized by elemental and thermal analyses and magnetic measurements. The Cu(II)–Nd(III) compound is stable up to 323 K. During dehydration process the water molecules are lost in two stages. The magnet...
