Procathepsin K can be activated by adjusting the pH 4.0 by adding an equal volume of 100 mM NaAc pH 3.9, 10 mM DTT, 5 mM EDTA followed by incubation for 40 min at RT. Activated mature Cathepsin is highly auto-proteolytic at pH 4.0, and care must be taken to avoid self-proteolysis. If the activated enzyme is not used immediately, we recommend to add methyl methanthiosulfonate (1 mM final concentration; MeS-SO2Me; MMTS) and to freeze the sample in liquid nitrogen or on dry ice. The hydrophobic thiol-reactive compound MMTS modifies cysteine′s by attaching its relatively small, uncharged thiomethyl-blocking group to reactive sulfhydryl groups (Nishimura et al., 1975). This reversible reaction arrests the auto-proteolytic process. The activity of the enzyme can be restored to nearly unmodified levels by adding L-cysteine (3M excess over MMTS) to the enzyme solution.

Gaucher disease is an inherited disorder caused by deficit of acid β-glucocerebrosidase, responsible for the degradation of glucosylceramide to ceramide and glucose. Although the disorder is primarily hematologic, bone is the second most commonly affected structure. Cathepsin K (CATK) is

Pycnodysostosis is a rare autosomal recessive skeletal dysplasia characterized by short stature, osteosclerosis, acro-osteolysis, frequent fractures, and skull deformities. Mutation in the gene encoding cathepsin K (CTSK), which is a lysosomal cysteine protease, has been found to be responsible for

Pycnodysostosis, an autosomal recessive skeletal dysplasia, is characterized by short stature, osteosclerosis, delayed cranial suture closure, hypoplastic mandible, acro-osteolysis, hypoplastic clavicle, and dental anomalies. The disorder is caused by CTSK gene defects, a gene localized on 1q21. To describe the

It is more than 50 years since the lysosome was discovered. Since then its hydrolytic machinery, including proteases and other hydrolases, has been fairly well identified and characterized. Among these are the cysteine cathepsins, members of the family of papain-like
