5 May 2009 The most potent virulence factors of this bacterium are the gingipains, three cysteine proteases that bind and cleave a wide range of host proteins.

The RCSB PDB also provides a variety of tools and resources. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists. sine-gingipain (Kgp) in the brain of Alzheimer's disease (AD) patients.1 Kgp is a cysteineproteasevirulencefactor secretedby Porphyromonas gingivalis, a keystone bacterium in the development of periodontal dis-ease.2 The secretion of gingipain proteases is part of the asaccharolytic Kgp gingipain activity was found to be more resistant to Sanggenol A (Table 2) compared to the Rgp gingipains. Sanggenol A up to 10µM had significantly less effect (P= 0.0017) on Kgp gingipain activity than on Rgp gingipain.

Cysteine endoproteinases, from periodontal pathogen PORPHYROMONAS GINGIVALIS, acting as virulence factors associated with PERIODONTITIS. They are Gingipain.

Gingipains are trypsin-like cysteine proteinases produced by Porphyromonas gingivalis, a major causative bacterium of adult periodontitis. HRgpA (95 kDa) and

Gingipain levels in AD brains were shown to significantly correlate with AD diagnosis and tau and ubiquitin pathology.

Its encoding region corresponds to 228-720aa of rgpA of Porphyromonas gingivalis-origin. This recombinant rgpA protein was validated … 2016-12-01 COR388 (atuzaginstat), a novel gingipain inhibitor, decreases ApoEfragmentation in the CNS of Alzheimer’s disease patients Debasish Raha1, Sean Broce1,Ursula Haditsch1,Leo Rodriguez1, Florian Ermini1, Michael Detke1, Shirin Arastu-Kapur1, Dave Hennings1, Mai Nguyen1, Leslie J. Holsinger1, Casey Lynch1, Stephen Dominy1 BACKGROUND It is, therefore, suggested that gingipain inhibition by vaccination and gingipain‐specific inhibitors is a useful therapy for adult periodontitis caused by P. gingivalis infection.

Porphyromonas gingivalis, a bacterium associated with active chronic periodontitis lesions, produces several proteolytic enzymes that are thought to be involved in host colonization, perturbation of the immune system, and tissue destruction. The GAIN (GingipAIN Inhibitor for Treatment of Alzheimer’s Disease) Trial is based on a growing body of scientific evidence that the bacteria P. gingivalis, most commonly associated with degenerative gum disease, can infect the brain and cause Alzheimer’s disease. The investigators, including Stephen Dominy, MD, the chief scientific officer of Cortexyme, which has developed a gingipain inhibitor, CORE-388, identified the pathogen in the brains of patients with Alzheimer disease, as well as the organism’s gingipains—lysine-gingipain (Kgp), arginine-gingipain A (RgpA), and arginine-gingipain B (RgpB)—in the neurons of these patients.

HRgpA (95 kDa) and RgpB (50 kDa), products of 2 distinct but related genes, rgpA and rgpB, respectively, are specific for Arg-Xaa peptide bonds. Kgp, a product of the kgp gene, is specific for Lys-Xaa bonds. Growth studies with site-directed gingipain-deficient mutants ofP. gingivalis revealed that inactivation of both gingipains prevents growth, whereas inactivation of either Arg- or Lys-gingipain activity extended the doubling times to 33 or 13 h, respectively, compared to 9 h for the parent strain.
