Abstract

In this mini-review we focus on metal interactions with proteins with a particular emphasis on the evident synergism between different biophysical approaches toward understanding metallobiology. We highlight three recent examples from our own laboratory. Firstly, we describe metallodrug interactions with glutathione S-transferases, an enzyme family known to attack commonly used anti-cancer drugs. We then describe a protein target for memory enhancing drugs called insulin-regulated aminopeptidase in which zinc plays a role in catalysis and regulation. Finally we describe our studies on a protein, amyloid precursor protein, that appears to play a central role in Alzheimer's disease. Copper ions have been implicated in playing both beneficial and detrimental roles in the disease by binding to different regions of this protein.
