Porphyromonas gingivalis Gingipains: The Molecular Teeth of a Microbial Vampire

Abstract excerpt

The gingipains are cell surface Arg- and Lys-specific proteinases of the bacterium Porphyromons gingivalis, which has been associated with periodontitis, a disease that results in the destruction of the teeth-s supporting tissues. The proteinases are encoded by three genes designated rgpA, rgpB and kgp. Arg-specific proteolytic activity is encoded by rgpA/B and the Lys-specific activity by kgp. RgpA and Kgp are...
