Visão geral

Pronase E can be used to degrade antheraea pernyi silk fibroin films.

A mixture of at least three proteolytic activities including an extracellular serine protease. In general, serine proteases display a wide range of substrate specificities, which are believed to be mediated by an active site composed of one Asp, one His, and a Ser residue in the molecule. This enzyme prefers to hydrolyze peptide bonds on the carboxyl side of glutamic or aspartic acid.

Completely inactivated by heating above 80 °C for 15-20 minutes.

Protease is typically used in nucleic acid isolation procedures in incubations of 0.5-3.0 hours supplemented with 0.2% sodium dodecyl sulfate and 10 mM EDTA.

This enzyme is useful for proteolysis of insoluble protein and for structure investigation of protein. Proteases from Streptomyces griseus and Streptomyces omiyaensis have been used in a study to identify residue 71 as a crucial residue for differences in topological specificities. Proteases have also been used in a study to investigate production of protease as a by-product of streptomycin production.
