Here we analyze the first complete genome sequence of Pyrococcus chitonophagus. The archaeon was previously suggested to belong to the Thermococcus rather than the Pyrococcus genus. Whole genome phylogeny as well as whole proteome comparisons using all available complete genomes in Thermococcales clearly showed that the species belongs to the Pyrococcus genus. P. chitonophagus was originally isolated from a hydrothermal vent site and it has been described to effectively degrade chitin debris, and therefore is considered to play a major role in the sea water ecology and metabolic activity of microbial consortia within hot sea water ecosystems. Indeed, an obvious feature of the P. chitonophagus genome is that it carries proteins showing complementary activities for chitin degradation, i.e. endo- and exo-chitinase, diacetylchitobiose deacetylase and exo-β-D glucosaminidase activities. This finding supports the hypothesis that compared to other Thermococcales species P. chitonophagus is adapted to chitin degradation.
