Functional curation of the Sulfolobus solfataricus P2 and S. acidocaldarius 98-3 complete genome sequences

The thermoacidophiles Sulfolobus solfataricus P2 and S. acidocaldarius 98-3 are considered key model organisms representing a major phylum of the Crenarchaeota. Because maintaining current, accurate genome information is indispensable for modern biology, we have updated gene function annotation using the arCOGs database, plus other available functional, structural and phylogenetic information. The goal of this initiative is continuous improvement of genome annotation with the support of the Sulfolobus research community.
