Exogenous addition of histidine reduces copper availability in the yeast Saccharomyces cerevisiae

Exogenous addition of histidine reduces copper availability in the yeast Saccharomyces cerevisiae – INTRODUCTION Free amino acids play pivotal roles as building blocks of proteins, as intermediates in metabolism, and also as regulators of a wide variety of cellular functions. In our previous studies, several amino acids including proline and arginine show cryoprotective activity in the budding yeast Saccharomyces cerevisiae . We recently showed that, under oxidative stress conditions, increased conversion (...)
