Heat Resistant Proteolytic Enzymes from Bacterial Sources

Proteolytic enzymes.

Leipner, J. and R. Saller (2000). "Systemic enzyme therapy in oncology: effect and mode of action." Drugs 59(4): 769-80. Plant extracts with a high content of proteolytic enzymes have been used for a long time in traditional medicine. Besides proteolytic enzymes from plants, 'modern' enzyme therapy additionally includes pancreatic enzymes. The therapeutic use of proteolytic enzymes is partly ba...

Proteolytic enzymes.

Proteolytic enzymes from extremely halophilic bacteria.

Halobacterium strains produce a truly extracellular proteinase which degrades gelatine and casein. It has a pH optimum of about 8 and depends upon divalent cations and a high concentration of NaCl or KC1 for activity and stability. Proteolytic enzymes were also found in cell homogenates obtained by ultra sonic treatment. A caseinolytic enzyme, probably different from the extracellular one, is a...

Functional Screening of Phosphatase-Encoding Genes from Bacterial Sources

Phosphatase (APase) enzymes including phytases have broad applications in diagnostic kits, poultryfeeds, biofertilizers and plant nutrition. Because of high levels of sequence diversity among phosphatases,an efficient functional screening method is a crucial requirement for the isolation of the encodinggenes. This study reports a functional cloning screening method for the iso...

Proteolytic enzymes of lung.

The lung usually is considered to be a passive tissue whose main function is to permit gaseous diffusion to and from the blood; however, the lung is also an organ of defense. Its phagocytes remove inhaled dust particles and bacteria. A considerable part of the lung parenchyma consists of mononuclear phagocytes and potential mononuclear phagocytes. Since these cells are not readily available in ...
