Structural highlights
FunctionKGP83_PORGN Cysteine proteinase with a strong preference for substrates with Lys in the P1 position. Hydrolyzes bovine hemoglobin, bovine serum albumin, casein, human placental type I collagen and human IgA and IgG. Disrupts the functions of polymorphonuclear leukocytes. May act as a virulence factor in the development of peridontal disease. Involved in the coaggregation of P.gingivalis with other oral bacteria (By similarity).[UniProtKB:B2RLK2] Publication Abstract from PubMedThe oral pathogen Porphyromonas gingivalis is a keystone pathogen in the development of chronic periodontitis. Gingipains, the principle virulence factors of P. gingivalis are multidomain, cell-surface proteins containing a cysteine protease domain. The lysine specific gingipain, Kgp, is a critical virulence factor of P. gingivalis. We have determined the X-ray crystal structure of the lysine-specific protease domain of Kgp to 1.6 A resolution. The structure provides insights into the mechanism of substrate specificity and catalysis.
