Abstract

This project will focus on two aspects of nitrate and nitrite utilisation: how nitrate and nitrite are transported across the E. coli cytoplasmic membrane; and how the presence of nitrate and nitrite ions is signalled in both E. coli and Neisseria gonorrhoeae. The first major objective is to identify the determinants of nitrate and nitrite transport in NarK, NarU and NirC from E. coli, and how the transporters distinguish between them. A bacterial two-hybrid system will be used to detect intra- and inter-subunit interactions within and between subunits of NarK, NarU and NirC. Further objectives will be to identify the determinants of the nitrate/nitrite specificity in NarX and NarQ; and reveal the molecular basis of the discrimination.
