Abstract

The E. coli mismatch uracil glycosylase (MUG) has been shown to cleave uracil, thymine and ethenocytosine from mismatches with guanine. However, it is not clear whether MUG is responsible for repairing these lesions in vivo. The aim of this project is it to investigate the action of MUG with a variety of different substrates both in vitro and in vivo. By using in vitro assays we can determine the binding affinity of MUG for different DNA lesions as well as the rate of N-glycosyl hydrolysis. An in vivo assay will then be used to investigate the action of MUG with the same DNA lesions against different genetic backgrounds. The combination of both in vitro and in vivo assays will allow the cellular function of MUG to be investigated, based upon a detailed understanding of its molecular mechanism.
