Abstract

The additionofa fibrinolytic enzymefrom Bacillus to afoodsystemcontributestoits functionality andmayhelpinpreventiveprophylaxisofthrombosis-relateddisorders.In the presentstudy,a fibrinolyticserine-metalloproteasewithsubstratespecificity was identified andpartiallypurified from Bacillus circulans CFR11. Theenzymewasactive toward α-chain moietyofhuman fibrinandAα and Bβ chains of fibrinogen andwastermed as CFR11-protease.Withthespecific activityof1399.57U/mgofprotein,maximumactivity of enzymewasobservedatpH7.4andtemperatureof50 1C. DivalentcationsMg2þ and Mn2þ were foundtoenhanceproteaseactivitybutitwasinhibitedbyphenylemethyl sulphonyl fluoride (PMSF)andethylenediaminetetraaceticacid(EDTA).Fromthedata obtained, theenzymehadanapparentmolecularweightof190kDaasperSDS-PAGE analysis andzymography.The in-vitro Activated PartialThromboplastinTime(APTT)and Prothrombin Time(PT)valuesshowednosignificant differenceinbothdoseandtime- dependent assay,inferringthesaferpropertyoftheCFR11enzymeforthrombolytic purpose. FromtheseresultsitcanbeconcludedthatanewenzymeCFR11protease, isolated withspecificity towards α-chain moietyof fibrin, canbecomeaneffective fibrin specific agentforthesafeprophylaxisofthrombosis.
