Interactions of gold-based drugs with proteins: crystal structure of the adduct formed between ribonuclease A and a cytotoxic gold(III) compound

Metallomics. 2014 Feb;6(2):233-6. doi: 10.1039/c3mt00265a.

Abstract

The reaction of Auoxo6, a dinuclear gold(III) complex, with the model protein bovine pancreatic ribonuclease is explored here by X-ray diffraction and ESI mass spectrometry. Data provide clues on the processes of adduct formation and of enzyme inhibition and, inductively, on the likely mode of action of this metallodrug.
