== Publication Abstract from PubMed == | |||
The reaction between cis-diamminedichloroplatinum(II) (CDDP), cisplatin, a common anticancer drug, and bovine pancreatic ribonuclease (RNase A), induces extensive protein aggregation, leading to the formation of one dimer, one trimer and higher oligomers whose yields depend on cisplatin/protein ratio. Structural and functional properties of the purified platinated species, together with their spontaneous dissociation and thermally induced denaturation, have been characterized. Platinated species preserve a significant, although reduced, ribonuclease activity. The high resistance of the dimers against dissociation and the different thermal unfolding profiles suggest a quaternary structure different from those of the well-known swapped dimers of RNase A. | |||
