Chemische Eigenschaften
These are proteolytic enzymes which take the form of light-colored, free-flowing powders. A protein containing numerous amino acids
Verwenden
This is a proteolytic enzyme isolated from the fermentation of Bacillus licheniformis. It is a serine endoproteinase with a broad specificity towards native and denatured proteins, and is active under alkaline conditions. It is for use in Total Dietary Fiber Assays (TDF-100A).
Verwenden
Protease from Bacillus sp. has been used to determine its proteolytic activity by spectrophotometric method.
Verwenden
Protease from Bacillus licheniformis has been used to digest the neurolemma in the antennal lobe of the moth; Heliothis virescens.
Allgemeine Beschreibung
Proteolytic enzymes are known to possess catalytic, non-catalytic and ancillary domains. Proteases are broadly classified as endopeptidases and exopeptidases. Functionally they are divided as aspartic, glutamic, cysteine, threonine, serine and metalloproteases.
Biochem/physiol Actions
Protease catabolizes proteins by hydrolysis of peptide bonds. Proteases are inactivated by serine active-site inhibitors, such as phenylmethylsulfonyl fluoride (PMSF) and diisopropylfluorophosphate. Proteases, secreted from Bacillus sp., typically have molecular weights ranging from 20,000 to 30,000. They are typcially stabilized by Ca2+ and have high isoelectric points.
Sicherheitsprofil
Moderately toxic by ingestion. Aneye irritant. When heated to decomposition it emits toxicfumes of NOx.
mögliche Exposition
These commercial proteolytic enzymes are used in laundry detergent formulations
läuterung methode
This alkaline protease is purified 211-fold by affinity chromatography using 4-(4-aminophenylazo)phenylarsonic acid complex to activated CH-Sepharose 4B. It is inhibited by 2-phenylethane boronic acid, PMSF, 3,4-dichloroisocoumarin, acetone and benzamide. [Chandraskaren & Dhar Anal Biochem 150 141 1985, Schomburg & Schomburg Springer Handbook of Enzymes 2nd Edn vol 7 p 286 2002.] Synexin (from bovine liver) M 47,000 Da. This Ca binding protein is purified by (NH4)2SO4 precipitation, then by a specific pH step elution from a chromatofocusing medium in the absence of ampholytes. The pI is 7.5. [Scott et al. Anal Biochem 149 163 1985.]
Inkompatibilitäten
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
