Allgemeine Beschreibung
If the activated enzyme is not used immediately, it is recommended to add methyl methanthiosulfonate (1 mM final concentration MMTS).
Note: 1 mU = 1 milliunit.
Recombinant, human procathepsin K (amino acids 19-329) (GenBank target symbol = S79895, ACC No. P43235) expressed in E. coli with a methionine residue inserted at amino acid 18 to create a new N-terminal initiation site. Cathepsin K, a member of the papain superfamiliy of cysteine proteinases, plays an important role in osteoclast-mediated bone resorption and collagen degradation. Cathepsin K is synthesized as an inactive proenzyme that is converted to its mature, active form by proteolytic cleavage of the 99 amino acid propeptide domain. Inhibitors of cathepsin K include leupeptin (Cat. No. 108975) (IC50 = 70 nM), E-64 (Cat. No. 324890) (IC50 = 5 nM), and cystatin (Cat. No. 324891 or 324896). Requires activation prior to use.

Warnhinweis
Toxicity: Standard Handling (A)
Einheitendefinition
One unit is defined as the amount of enzyme that will hydrolyze 1 µmole benzyloxycarbonyl-phenylalanine-arginine-7-amido-4-methylcoumarin per min at 37°C, pH 5.5.
Physikalische Form
In 500 mM NaCl, 25 mM Tris, pH 8.0.
Rekonstituierung
Following initial thaw, aliquot and freeze (-70°C). Following activation the enzyme is unstable and should include MMTS for storage (see recommended reaction conditions for activation).
