Description and significance
Thermotoga neapolitana cells are gram-negative rods, aproximately 1.5 to 11 ~tm long and 0.6 Ixm wide, and can occur singly and in pairs. They have an unusually thick periplasmic cell wall layer, which, when compared with characteristic gram-negative cell walls, is covered with a more electron-dense outer layer. Cells are immotile, possesing no flagella. They are surrounded by a sheath-like outer structure that usually balloons over the ends; a "toga," as it were, from which the genus name is derived. Its species name is in reference to the location of its original isolation in 1986: a shallow marine sediment in a volcanic region near Lucrino, Bay of Naples, Italy.
Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them.
Describe the size = 1800 Kb and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?
Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.
As an extremely thermophilic eubacteria, Thermotoga neapolitana is not viable under the conditions that support most life. It therefore has no known diseases associated with it, and at present has not been found to be pathogenic.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
