Query: NC_009482:822716 Synechococcus sp. RCC307 chromosome, complete genome
Lineage: Synechococcus; Synechococcus; Synechococcaceae; Chroococcales; Cyanobacteria; Bacteria
General Information: Marine Synechococcus and Prochlorococcus are the most abundant photosynthetic organisms on earth and between them account for about half of the world's photosynthesis. RCC307 is an oceanic Synechococcus strain which presents great phylogenetic interest because trees obtained using its 16S RNA gene seem to indicate that it is rooted at the base of the radiation of marine cyanobacteria. This strain was isolated from seawater taken at a depth of 15 meters from the Mediterranean Sea.
Subject: 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.
