Abstract

We will use fluorescence spectroscopy, surface plasmon resonance and ultracentrifugation to investigate the molecular details of promoter DNA melting by the activator-dependent sigma factors, sig54 and sigL. Fluorophores will be incorporated into both the DNA, via 2-aminopurine substitution, and the protein, via covalent modification of site-specifically inserted cysteine residues. These experiments will be used to derive the kinetic rates for the various steps involved in sigma induced isomerisation, as well as probing the concomitant conformational changes, e.g. via FRET.
