Abstract
The interaction of DNA with CopperIIGlutathione CuGSH has been investigated by various biophysical methods The interaction ratio of DNA and CopperIIGlutathione in solution phase has been determined spectrophotometrically and found to be 025 EPR spectroscopy and UV–Vis findings suggest that CuIIGlutathione neither bound to the DNA bases covalently nor intercalated this has further been substantiated by the determination of intrinsic binding constant 21 × 102 Viscometric measurements also support this type of binding to DNA by CuIIGlutathione EPR studies and visible d–d spectra of CuGSH after interaction with DNA suggested that Copper remained in the CopperII state DNA conformations after interaction with CuIIGlutathione has been determined spectroscopically Circular dichroism studies revealed that the B conformation of DNA is changed to A after interaction with CuIIGlutathione This has further been substantiated by thin film IR Infrared studies
