Cysteine protease cathepsin
WebCysteine proteases are lysosomal enzymes of the papain family, among which cathepsin K, B, L, and S are regarded as the most relevant to the development of OA. The role of cathepsin K, which degrades both type II collagen and aggrecan in articular cartilage in the pathophysiological progression of OA, has been well documented previously ... WebOct 1, 1995 · The protease displays an inhibition profile typical for cysteine proteases and is highly active against synthetic peptide substrates. The pH optimum of the bell-shaped pH-activity curve is between 5.0 and 5.5. The best substrate tested is Z-Arg-Arg-MCA which is specific for cathepsin B.
