Chem. 287:23971-23976(2012). CC -!- FUNCTION: In the mammalian host activates (cleaves) plasminogen to CC generate the serine protease plasmin. Plasmin degrades fibrin clots CC (fibrinolysis) and facilitates bacterial cell migration, enabling rapid CC dissemination of bacteria from the initial site of infection CC (Probable). Cleaves host plasminogen to generate plasmin and probably CC also has autocatalytic activity (PubMed:20637417, PubMed:22645135). CC Fibrinolytic activity prevails at 37 degrees Celsius whereas coagulase CC expression predominates at lower temperatures (28 degrees Celsius) CC (PubMed:2526282). Cleaves plasminogen; plasminogen cleavage is much CC higher than coagulase activity (PubMed:20637417, PubMed:22645135, CC PubMed:2526282, PubMed:2651310). {ECO:0000269|PubMed:20637417, CC ECO:0000269|PubMed:22645135, ECO:0000269|PubMed:2526282, CC ECO:0000269|PubMed:2651310, ECO:0000305|PubMed:17635705}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Converts human Glu-plasminogen to plasmin by cleaving the 560- CC Arg-|-Val-561 peptide bond that is also hydrolyzed by the mammalian CC u-plasminogen activator and t-plasminogen activator. Also cleaves CC arginyl bonds in other proteins.; EC=3.4.23.48; CC Evidence={ECO:0000269|PubMed:22645135}; CC -!- ACTIVITY REGULATION: Requires bacterial lipopolysaccharide (LPS) for CC activation; addition of LPS to inactive protein reactivates it CC (PubMed:20637417). In the absence of LPS the active site groove is CC slightly narrower, and peptide substrate binds deep within the active CC site groove, displacing the nucleophilic water molecule CC (PubMed:22645135). {ECO:0000269|PubMed:20637417, CC ECO:0000269|PubMed:22645135}. CC -!- BIOPHYSICOCHEMICAL PROPERTIES: CC pH dependence: CC Optimum pH is 6-7 for plasminogen cleavage (PubMed:20637417). CC {ECO:0000269|PubMed:20637417}; CC -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000305|PubMed:20637417, CC ECO:0000305|PubMed:2526282}; Multi-pass membrane protein CC {ECO:0000269|PubMed:20637417, ECO:0000269|PubMed:22645135}. CC -!- DOMAIN: Forms a narrow, elliptical 10-stranded beta barrel with the CC active site pairs on the extracellular surface (PubMed:20637417, CC PubMed:22645135). {ECO:0000269|PubMed:20637417, CC ECO:0000269|PubMed:22645135}. CC -!- DISRUPTION PHENOTYPE: 90% survival of infected mice, mice develop a CC robust immune defense (PubMed:17635705). {ECO:0000269|PubMed:17635705}. CC -!- SIMILARITY: Belongs to the peptidase A26 family. {ECO:0000305}.
