HAMAP: Uncultured termite group 1 bacterium phylotype Rs-D17 complete proteome
General information

Species:  Uncultured termite group 1 bacterium phylotype Rs-D17
Species code: UNCTG
Taxonomy: Bacteria; Elusimicrobia; environmental samples (TaxID: 471821) [NEWT/ NCBI]
Description: Termites have an extensive symbiosis with many organisms which allows them to digest cellulose, their food. To do so they rely on symbiotic protozoa, such as Trichonympha, and other microbes in their gut to digest the cellulose. They protozoa in turn depend on bacteria to produce some of the necessary digestive enzymes. The symbiotic bacteria are so far unculturable, and thus known mostly from their 16S rRNA sequences. Phylotype Rs-D17 is a member of the Termite Group 1 bacteria (TG1), one of the prominent groups of bacteria in the termite gut. It is found specifically within the cells of the cellulolytic flagellate Trichonympha agilis in the gut of the termite Reticulitermes speratus. Approximately 4,000 Rs-D17 cells are housed within each host cell, accounting for 4%, in total, of all of the prokaryotic cells in the gut. To obtain this genome sequence part of the bacterial contents of one leaking protozoan cell was isolated. The bacteria probably supplies it host(s) with amino acids and cofactors. It probably produces a weak cell wall as many of the genes involved are pseudogenes, and it stains as a weak gram-negative (adapted from PubMed 18391199 and Wikipedia).
