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.

Re-cently, a hemoglobin binding protein called HbR, intrageni-cally encoded by the rgpA, kgp, and hagA genes, has been identiﬁed (35).

This gingipain R structure is an excellent template for the rational design of drugs with a potential to cure and prevent periodontitis. Here we show the binding mode of an arginine-containing inhibitor in the active-site, thus identifying major interaction sites defining a suitable pharmacophor.

This mechanism is dependent on both Rgp type gingipain released from P. gingivalis, and PARs in an interaction with the α2A adrenergic

This Recombinant Porphyromonas gingivalis Gingipain R1 (rgpA) with N-terminal 6xHis-tags is a partial protein expressed in yeast. Its encoding region corresponds to 228-720aa of rgpA of Porphyromonas gingivalis-origin. This recombinant rgpA protein was validated through SDS-PAGE and LC-MS/MS Analyses. gingipain has been observed to possess hemolytic activity (43), the role of Lys-gingipain in hemolysis remains unknown. Re-cently, a hemoglobin binding protein called HbR, intrageni-cally encoded by the rgpA, kgp, and hagA genes, has been identiﬁed (35). In addition, the Lys-gingipain has shown he-moglobin binding activity (28). In ex vivo studies, it was shown that gingipain K retained its IgG hydrolyzing activity in human plasma despite the high content of natural protease inhibitors; that IgG(1) cleavage products were detected in gingival crevicular fluid samples from patients with severe periodontitis; and that gingipain K treatment of serum samples from patients with high antibody titers against P. gingivalis 3,4 Gingipains have been described and studied as being particularly efficient and versatile enzymes, capable of proteolysis of several host molecules associated Two major classes of extracellular cysteine proteases specific for Arg-X and Lys- X peptide bonds [Arg-gingipains (RGPs) and Lys-gingipain (KGP)] have been 20 Mar 2019 Gingipains are detected at concentrations exceeding 100 nM in gingival crevicular fluid from P. gingivalis-infected periodontitis sites, where 18 Jul 2014 P. gingivalis is a gram negative, assacharolytic, black pigmented bacterium armed with a pleothera of virulence factors such as This organism produces potent cysteine proteases known as gingipains, which have specificity for cleavage after arginine or lysine residues.

RASMCs were exposed to 200, 100, 50, 25, 12, 6, 3, 1, and 0 μg/mL activated gingipains and 2019-01-01 Rgp gingipain activity was calculated as percent inhibition of the control RFU/min/ml values of the control (in the absence of Sanggenol A). Kgp gingipain activity was found to be more resistant to Sanggenol A (Table 2) compared to the Rgp gingipains.

From $88 Leupeptin, an Arg-gingipain-specific protease inhibitor, almost completely inhibited collagen degradation by P. gingivalis cells whereas cathepsin B inhibitor II, a Lys-gingipain inhibitor, did not. A purified preparation of Arg-gingipains A and B hydrolyzed gelatin but did not cleave type I collagen, suggesting that the enzymes must be attached to the cell surface to exert collagenase activity.
