Abstract

The regulator of mercury resistance genes, MerR, is the archetype of a new family of prokaryotic transcriptional regulators with related N-terminal DNA binding regions. We wish to test the hypothesis that MerR acts through Hg-dependent interconversion of a repressor and activator form and begin the structural determination of the protein. We will use recombinational mutagenesis to generate new constitutive activator mutations, constitutive repressor mutations and to alter the metal ion specificity, and we will investigate expressing MerR subdomains for structural studies. The properties of the mutant and subdomain proteins will be characterised.
