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.
Application
Protease is an enzyme used to break down proteins by hydrolyzing peptide bonds. Protease is used to degrade proteins, to study protease inhibitors and to study thermal inactivation kinetics. Protease is used in nucleic acid isolation procedures in incubations.
Biochem/physiol Actions
Alcalase is an endo-protease of the serine type. It has a broad substrate specificity and can hydrolyze most peptide bonds within a protein molecule. It is active between pH 6.5 and 8.5 and has an optimum temperature of 60 °C. The enzyme is is used in detergent formulations to remove protein-based stains.
Protease catabolizes proteins by hydrolysis of peptide bonds. Proteases are inactivated by serine active-site inhibitors, such as phenylmethylsulfonyl fluoride (PMSF) and diisopropylfluorophosphate .

What is the concentration of the product, and how can the conversion from units/g on the COA to units/ml be performed?
1 respuesta-
The density of the Novozymes product, as indicated in the SDS sheet, is 1.17g/ml. By multiplying 1.17 g/ml (density) by 50 ml (pack size), 58.5 g of the solution is obtained. Further multiplication with 2.55 unit/g (lot activity) results in 149.175 or 149.2 units. Dividing 149.2 units by 50ml gives 2.984 units/ml.
