We initiated studies on the E. coli Direct Oxygen Sensor protein, Dos, in 2001. We originally cloned the gene out of E. coli strain K12, as the Gilles-Gonzalez group originally described in the literature. Much of our work remains unpublished, however in 2004 our structure of the Dos Heme Domain (DosH) was published in Biochemistry. Subsequently Posters and PowerPoint presentations about the DosH Structure have been presented. These can be found in the Posters and Talks sections of the site. As we continue to improve and expand this page, and publish further Dos and DosH results, this section will be expanded in the future.
