NEW MOLECULAR TOOLS TO STUDY THE MECHANISMS OF BACTERIAL METAL HOMEOSTASIS

Grant number: FT170100006 | Funding period: 2018 - 2021

Abstract

This project aims to provide new insight into how metal ion uptake is regulated. It will precisely measure the cellular concentrations of metal ions, reveal the roles of metal ions in essential cellular processes, and identify the molecular targets of metal toxicity. Metal ions are essential to all forms of life and are used by up to half of all proteins to facilitate cellular chemical processes. The intended outcome of the research is to provide new fundamental knowledge of the roles of metal ions in bacterial cells; knowledge that will be key to defining the chemical biology of living systems and will provide information essential to understanding how microbes adapt to changing environment..
