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

Prothrombin Time(PT)valuesshowednosignificant differenceinbothdoseandtime-
dependent assay,inferringthesaferpropertyoftheCFR11enzymeforthrombolytic

isolated withspecificity towards α-chain moietyof fibrin, canbecomeaneffective fibrin
