Abstract

Genetic exchange in bacteriophages regularly occurs at aberrant sites leading to rearrangement of existing genes or acquisition of new ones. This relaxed fidelity has important consequences for the rate of evolutionary change and the transmission of virulence components between species. We will examine the interplay between a novel DNA binding protein, orf, and recombinases from phage lambda and its host bacterium using stopped-flow fluorescence spectroscopy and electrophoretic mobility shift assays. Loading and unloading of these proteins at the junction between strands and duplexes is likely to be crucial in determining whether annealing or invasion pathways of recombination predominate. The results will offer fresh insights into the mechanisms of recombination responsible for modulating phage genome organisation.
