Tannerella forsythensis ATCC 43037
Gene Image Map
Tannerella forsythensis is an anaerobic Gram-negative member of the Cytophaga-Bacteroides family implicated in periodontal diseases. T. forsythensis, P. gingivalis and T. denticola form a "red complex" of species associated with aggressive periodontal infections (Socransky et al., 1998; Holt and Ebersole, 2000). This organism was described as Bacteroides forsythus 1986 (Tanner et al. 1986) and reclassified to Tannerella forsythensis based upon its phylogenetic position by Sakamoto et al. 2002. Distinguishing biochemical characteristics are reviewed in Sakamoto et al. A proposal has been made to have the epithet name revised to "forsythia" (Maiden et al., 2003).
Strain ATCC 43037 was provided by Floyd Dewhirst and Mark F. J. Maiden at The Forsyth Institute. The resulting sequence was provided prior to publication by Steve Gill and colleagues at the TIGR Institute ("Genome analysis of Bacteroides forsythus" NIH/ National Institute of Dental and Craniofacial Research (U01-DE13914) awarded to TIGR; Steven R. Gill, PI.) We thank Dr. Anne Tanner of The Forsyth Institute for providing helpful background information and references.

The core information in this database is the table of annotated records, one for each of the 3034 predicted open reading frames. Annotation of the completed genome made use of penta-directional comparisons with the dentoti database and with BLAST similarities to the NR database. Each gene record is identified by a gene id, TF0001-TF3165. Basic summaries of specific information are available below in the Predefined Database Searches and contain links to the complete gene record. At this time, GenBank entries are not available for this genome.
For a general perspective of the genome, we recommend you go to the Gene Image Map and browse blocks of coordinates. Caution: The entire TF genome can be viewed at one time, however this large file can cause some machines to freeze. Browsing and searching are also facilitated by the Functional Classes, EC Table, and Biochemical Pathways summaries. For precise inquiries on the other hand, start with the search capabilities and their associated tables. Fuller analyses of the proteome are underway, for example a table of proteins found in the Bacteroides-related proteome comparison section of the database.
