Aktivnost ovog enzima stimuliše glicin. Reference ^ 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 Gingipains are the products of 3 genes which encode cystein proteinases. Gingipains are of two types: a) Gingipain –R : which hydrolyse Arg-Xaa bond b) Gingipain- K: which hydrolyse Lys-Xaa bond 22 June 2015 6 GENE GINGIPAIN Enzymes rgpA gene gingipain R with hemagglutinin/adhesi on domains 1) RgpA(cat) 2) mt-RgpA 3) HRgpA rgpB gene Gingipain R without adhesion domains 1) RgpB 2) mt-RgpB kgp ABSTRACT Degradation of immunoglobulins is an effective strategy of bacteria to evade the immune system. We have tested whether human IgG is a substrate for gingipain K of Porphyromonas gingivalis the critical roles of gingipain R and gingipain K in the viru-lence of Porphyromonas gingivalis [ ]. Protease gingipain R existsas-, -,and -to -and-kDaproteins,the rst two being a complex of the -kDa catalytic subunit with hemagglutinin/adhesins, with or without an added mem-brane anchorage peptide. e other forms are single-chain enzymes.

In ex vivo studies, it was shown that gingipain K retained its IgG hydrolyzing activity in human plasma despite the high content of Cleavage of IgG1 and IgG3 by gingipain K from Porphyromonas gingivalis may compromise host defense in progressive periodontitis. Research output: Contribution to journal › Article Two peptidases, gingipain K (Kgp) and R (RgpA and RgpB), which differ in their selectivity after lysines and arginines, respectively, collectively account for 85% of the extracellular proteolytic activity of P. gingivalis at the site of infection. Therefore, they are promising targets for the design of specific inhibitors. 2017-04-07 · Structural insights unravel the zymogenic mechanism of the virulence factor gingipain K from Porphyromonas gingivalis, a causative agent of gum disease from the human oral microbiome.
