Query: NC_007484:3035068 Nitrosococcus oceani ATCC 19707, complete genome
Lineage: Nitrosococcus oceani; Nitrosococcus; Chromatiaceae; Chromatiales; Proteobacteria; Bacteria
General Information: Found in marine or saline environments. Ammonia-oxidizing bacterium. This species, along with Nitrosococcus halophilus, are ammonia-oxidizing bacteria found within the gamma subdivision of Proteobacteria. This organism has two surface layers, and produces a central stack of intracytoplasmic membranes (flattened vesicles).
Subject: NC_008576:4130000 Magnetococcus sp. MC-1, complete genome
Lineage: Magnetococcus marinus; Magnetococcus; Magnetococcaceae; Magnetococcales; Proteobacteria; Bacteria
General Information: This magnetotactic bacterium was isolated from water from the Pettaquamscutt Estuary, in Rhode Island, USA. Migration is towards the anoxic/oxic interface which in the case of Magnetococcus sp. MC-1 is in a polar direction. The genome sequence of this organism will provide information on the production and regulation of the proteins involved in the magnetosome.
