RESUMO

The target for sordarins in Candida albicans has been elucidated. Kinetic experiments of sordarin inhibition as well as displacement experiments showed that the formation of a sordarin-target complex follows a reversible mechanism. Binding of tritiated drug to the target is enhanced in the presence of ribosomes. Isolation of the target by classical protein purification methods has allowed us to identify it as elongation factor 2. This is in agreement with the nature of sordarin derivatives as specific inhibitors of the elongation cycle within protein synthesis in yeasts.
