Query: NC_007426:205390 Natronomonas pharaonis DSM 2160, complete genome

Lineage: Natronomonas pharaonis; Natronomonas; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea

General Information: Isolated from Lake Gabara in Egypt. Extreme haloalkaliphilic archeon. Natronomonas pharaonis is able to survive at high salt and pH conditions which results in limited nitrogen availability through ammonium. In order to compensate for this, Natronomonas pharaonis has developed three systems to promote nitrogen assimilation: direct uptake of ammonia, uptake of nitrate, and uptake of urea. Another problem with high pH environments is the use of a proton gradient for the generation of ATP, which other alkaliphiles have adapted to by substitution of sodium ions for protons. However, this organism utilizes protons for ATP generation as determined by experimental data.

Subject: NC_007643:185135 Rhodospirillum rubrum ATCC 11170, complete genome

Lineage: Rhodospirillum rubrum; Rhodospirillum; Rhodospirillaceae; Rhodospirillales; Proteobacteria; Bacteria

General Information: This bacterium can grow using carbon monoxide as the sole carbon and energy source and the cells contain a well characterized nitrogenase system that is post-translationally modified by ADP-ribosylation. Phototrophic bacterium. This organism is an anoxygenic phototrophic bacterium that does not produce oxygen, but instead produces extracellular elemental sulfur when harvesting light energy. The bacterium lacks the light harvesting complex 2 (LHC2) normally found in photosynthetic bacteria meaning it contains one of the simplest photosynthetic systems studied.
