Most enzymes bind specifically to one or to a few closely related substrates. However, this is not the case for the enzyme superfamily of glutathione S-transferases (GSTs). The enzyme's ability to recognise a diverse range of substrates is due, in part, to the existence of isoforms. We have determined the crystal structures of GSTs from four classes and from a diverse range of organisms ranging from bacteria to human. These studies are revealing the molecular basis and evolutionary development of how GSTs recognise and react with a structurally diverse array of toxins.
