You searched for: Enzymes

Enzymes accelerate, or catalyze, chemical reactions, and they are known to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Choose specific enzymes for cleaving bonds, removing genomic DNA from RNA preparations, for producing fragments of proteins, or for use in ion exchange chromatography. Enzymes are used in the chemical industry and other industrial applications when extremely specific catalysts are required.

Pronase E (from Streptomyces griseus)

Supplier: Merck

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.
