متن کاملIsolation, Purification and Characterization of a Thermophilic Alkaline Protease from Bacillus subtilis BP-36
The goal of this research was to isolate and identify the thermostable alkaline protease producing bacteria among several native Iranian microorganisms. At the end of screening program, a Bacillus subtilis BP-36 strain producing thermophilic alkaline protease was isolated from a hot spring in Ardebil province. The target enzyme was purified using a one-step Aqueous two-phase systems (ATPS) prot...
متن کاملProduction & purification of a fibrinolytic enzyme (thrombinase) from Bacillus sphaericus.
BACKGROUND & OBJECTIVE Treatment of thromboembolic vascular disease has relied on anticoagulants. However, recognition that lysis of preformed fibrin could be accomplished in vivo by a process involving the conversion of inactive plasminogen to active plasmin enzyme led to an alternative enzyme-based approach. The drugs used for this therapy are called the fibrinolytic enzymes. In this study we...
متن کاملProperties of meso - a , € - Diaminopimelate D - Dehydrogenase from Bacillus sphaericus
meso-a,eDiaminopimelate D-dehydrogenase, which has been purified to homogeneity from the extract of Bacillus sphaericus IF0 3626, has a molecular weight of about 80,000 and consists of two subunits identical in molecular weight (approximately 40,000). The enzyme has a high substrate specificity. In addition to mso-a,diaminopimelate, lanthionine is deaminated by the enzyme to a far lesser extent...
متن کاملProperties of crystalline leucine dehydrogenase from Bacillus sphaericus.
The distribution of bacterial leucine dehydrogenase (L-leucine:NAD+ oxidoreductase, deaminating, EC 1.4.1.9) was investigated, and Bacillus sphaericus (IFO 3525) was found to have the highest activity of the enzyme. Leucine dehydrogenase, which was purified to homogeneity and crystallized from B. sphaericus, has a molecular weight of about 245,000 and consists of six identical subunits (Mr = 41...
