Gingipain K cleaves exclusively on the C-terminal side of Lys in peptides and synthetic substrates [3,8]. Substrate turnover is affected by amino acids at the P2 position, which is most noticeable in the lack of either Arg-Lys↓Xaa or Lys-Lys↓Xaa peptide bond cleavage.

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 significantly hindered opsonin-dependent phagocytosis of clinical isolates of P. gingivalis by neutrophils. Porphyromonas gingivalis is a member of the dysbiotic oral microbiome and a "keystone pathogen" that causes severe periodontal disease, which is among the most prevalent infectious diseases. Part of the virulence factors secreted by P. gingivalis are the essential cysteine peptidases gingipain K (Kg … 2019-03-20 · Structural determinants of inhibition of Porphyromonas gingivalis gingipain K by KYT-36, a potent, selective, and bioavailable peptidase inhibitor Abstract. Porphyromonas gingivalis is a member of the dysbiotic oral microbiome and a “keystone pathogen” that causes Introduction. The human oral Start Studera Välja studier Anmälan och antagning Livet som student Internationella möjligheter Examen och karriär The Porphyromonas gingivalis lysine‐specific cysteine protease (gingipain K, Kgp) is expressed as a large precursor protein consisting of a leader sequence, a pro‐fragment, a catalytic domain with a C‐terminal IgG‐like subdomain (IgSF) and a large haemagglutinin/adhesion (HA) domain. 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.
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 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 Gingipain Cysteine Endopeptidases Engelsk definition.
