Mycobacteriophage L5 integrase-mediated site-specific integration in vitro.
Mycobacteriophage L5, a temperate phage of the mycobacteria, forms stable lysogens in Mycobacterium smegmatis via site-specific integration of the phage genome. Recombination occurs within specific phage and bacterial attachment sites and is catalyzed by the phage-encoded integrase protein in vivo. We describe here the overexpression and purification of L5 integrase and its ability to mediate integrative recombination in vitro. We find that L5 integrase-mediated recombination is greatly stimulated by extracts of M. smegmatis but not by Escherichia coli extracts, purified E. coli integration host factor, or purified HU, indicating the presence of a novel mycobacterial integration host factor.[1]References
