Query: NC_009720:2143124 Xanthobacter autotrophicus Py2, complete genome
Lineage: Xanthobacter autotrophicus; Xanthobacter; Xanthobacteraceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Alkene-degrading bacterium. Xanthobacter autotrophicus is a nitrogen-fixing methylotroph, commonly isolated from organic rich soil, sediment and water. This organism uses an alkene-specific monooxygenase to convert propene to epoxypropane. This monooxygenase is also able to catalyze the initial step in the cometabolism of chlorinated alkenes such as vinyl chloride and trichloroethene. The Xanthobacter autotrophicus alkene monooxygenase and other genes involved in alkene degradation are located on a 320 kb megaplasmid.
Subject: NC_009879:260000 Rickettsia canadensis str. McKiel, complete genome
Lineage: Rickettsia canadensis; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This organism was originally isolated from ticks in a field study on tick-transmitted diseases of small mammals in Canada. Member of the typhus group of Rickettsiales. Members of this genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, are obligate intracellular pathogens. In both groups, the bacteria are transmitted via an insect, usually a tick, to a host organism where they target endothelial cells and sometimes macrophages. They attach via an adhesin, rickettsial outer membrane protein A, and are internalized where they persist as cytoplasmically free organisms. Rickettsia canadensis was originally thought to be a member of the typhus group of Rickettsiales, however, it is now thought to represent a distict group with the rickettsia.
