Candidatus Ruthia magnifica
Description and significance
R. magnifica is a chemoautotrophic bacteria that lives symbiotically with a giant clam, a Metazoan with a genus and species of 'Calyptogena magnifica'. It lives in an environment that may be characterized as a hydrothermal vent. They use the chemical energy of reduced sulfur emanating from vents to provide their hosts with carbon and a large array of additional necessary nutrients such as essential amino acids and vitamins.[3] In return, the hosts provide the bacteria with inorganic substrates necessary for chemoautotrophic activity. R. magnifica itself lives in the gut and ciliary food groove of C. magnifica.[3] The sequencing of the R. magnifica genome is important in determining its metabolism and the compounds it is able to produce. Which, in turn, will give insight into the metabolism and biology of the host. R. magnifica is the first intracellular, sulfur-oxidizing endosymbiont to have its genome sequenced.[3]
Genome structure
R. magnifica has 1,119 that encode 1,953 proteins. A cingular circular chromosome contains genes which are predicted to encode all the proteins necessary for all the metabolic pathways typical of free-living chemoautotrophs, including carbon fixation, sulfur oxidation, nitrogen assimilation, amino acid and cofactor/vitamin biosynthesis.[3]
Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
Ecology
Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.
Pathology
Due to its need for sulfer to survive, it is not likely to find R. magnifica in the same environment as humans. Therefore, it is not considered a pathogen and is not currently thought to cause any disease.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
Current Research
Enter summaries of the most recent research here--at least three required
