== Publication Abstract from PubMed ==
 +
The model protein hen egg white lysozyme was challenged with oxaliplatin and cisplatin. ESI mass spectrometry, surface plasmon resonance and thermal shift analyses demonstrate the formation of a bis-platinum adduct, though in very small amounts. Crystals of the bis-platinum adduct were obtained using two different preparations and the X-ray structures were solved at 1.85 A and 1.95 A resolution. Overall, the obtained data point out that, under the analyzed conditions, the two Pt drugs have similar affinities for the protein, but bind on its surface at two non-overlapping sites. In other words, these two drugs manifest a significantly different reactivity with this model protein and do not compete for the same protein binding sites.
