Studies On The In Vitro Transposition Of Bacteriophage Mu Dna
The early steps in the transposition of Mu DNA have been examined in vitro using purified Mu A, Mu B and E. coli HU proteins, a mini-Mu donor plasmid and target DNA. Two stable protein-DNA complexes, or transpososomes, have been characterized. Type 1 complex formation requires a supercoiled mini-Mu …

The Integration and Excision Mechanisms of the Bacteroides Conjugative Transposon CTnDOT
A critical requirement for studying transposition is the availability of a defined in vitro transposition system. Using the partial-purified CTnDOT Int protein, an in vitro integration system was developed and a host factor(s) from Bacteroides cell extract was shown to be important for integration. …

Highly Saturated Transposon Sequencing identifies genes impacting Staphylococcus aureus pathogenesis in macrophages
Staphylococcus aureus is a facultative intracellular pathogen in many host cell types,facilitating its persistence in chronic infections. The genes contributing to intracellular pathogenesis have not yet been fully enumerated. Here, we cataloged genes influencing S. aureus invasion and survival …

Towards Novel Methods of Mutagenesis for Histophilus somni
Histophilus somni is an etiologic agent of shipping fever pneumonia, myocarditis, and other systemic diseases in bovines, although nonpathogenic commensal strains also exist. Virulence factors that have been identified in H. somni include biofilm formation, lipooligosaccharide phase variation, …
