Abstract
We are exploring the ability of genetically engineered versions of the Staphlococcus aureus αHL} ion channel to serve as rationally designed sensor components for analytes including divalent cations. We show here that neither the hemolytic activity nor the single channel current of wild type αHL were affected by [Zn(II)]
