prtRII | Arginine-specific cysteine proteinase; Thiol protease. Acts synergistically with RgpA to catalyze the maturation of fimbrial subunits, such as FimA (By similarity). Its proteolytic activity is a major factor in both periodontal tissue destruction and in evasion of host defense mechanisms (Probable). (736 aa) | ||||
hagA | Hemagglutinin protein HagA; Agglutinates erythrocytes. (2105 aa) | ||||
fimA | Fimbrilin; Structural subunit of the major fimbriae. These long, filamentous pili are attached to the cell surface; they mediate biofilm formation, adhesion onto host cells and onto other bacteria that are part of the oral microbiome. They play an important role in the invasion of periodontal tissues. Fimbriae and their constituents are major virulence factors. FimA proteins from different strains have highly divergent sequences, and this has been used for classification. The sequence-based classification correlates with pathogenicity; Belongs to the bacteroidetes fimbrillin superfamil [...] (388 aa) |
