  • proteases are among the most technically important enzymes of all. For detergents and cleaners, they are the longest established and contained in virtually all modern, powerful detergents and cleaners enzymes. They cause the degradation of protein-containing stains on the items to be cleaned. Of these, in turn, proteases of the subtilisin type (subtilases, subtilopeptidases, EC 3.4.21.62) are particularly important, which are due to the catalytically active amino acids serine proteases. They act as nonspecific endopeptidases and hydrolyze any acid amide linkages that are internal to peptides or proteins. Their pH optimum is usually in the clearly alkaline range.
