HAMAP: Azobacteroides pseudotrichonymphae genomovar. CFP2 complete proteome
General information

Species:  Azobacteroides pseudotrichonymphae genomovar. CFP2
Species code: AZOPC
Taxonomy: Bacteria; Bacteroidetes; Bacteroidia; Bacteroidales; Candidatus Azobacteroides (TaxID: 511995) [NEWT/ NCBI]
Description: Azobacteroides pseudotrichonymphae genomovar CFP2 was isolated from a single cell of the uncultivable cellulolytic protist Pseudotrichonympha grassii that resides in the gut of the termite Coptotermes formosanus. A. pseudotrichonymphae is probably required by its protist host for the biosynthesis of nitrogen compounds that are deficient in woody materials. The cellulolytic protist with its N2-fixing endosymbionts, in turn, enables highly efficient growth of the host termite and its colony without being limited by nitrogen deficiency. A. pseudotrichonymphae possesses a single circular chromosome and four circular plasmids. It is strictly anaerobic and cannot use oxygen as an electron acceptor, as the genome lacks genes for catalase, superoxide dismutase, and cytochrome oxidase. The discovery of genes for N2-fixing activity in a member of the Bacteroidetes is unexpected, as there have been no previous reports of nitrogenase genes in this phylum. This bacterium is known to take up molecular hydrogen which is abundantly produced during both lignocellulose fermentation and nitrogen fixation, and is an ideal alternative energy source. Moreover, the removal of excess molecular hydrogen theoretically promotes both lignocellulose fermentation and nitrogen fixation.
