      Description
      OverviewRecombinant, 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 superfamily 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.
      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.

      Revision27-September-2007 RFH
      DescriptionRecombinant, 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.
      FormLiquid
      FormulationIn 500 mM NaCl, 25 mM Tris, pH 8.0.
      Concentration Label Please refer to vial label for lot-specific concentration
      Recommended reaction conditions
      Activation 1. Add an equal volume of 100 mM sodium acetate buffer, 10 mM DTT, 5 mM EDTA, pH 3.9 and incubate at room temperature for 40 min. This will adjust the pH of the procathepsin K to 4.0. 2. If the activated enzyme is not to be used immediately, add methyl methanthiosulfonate (MeS-SO2Me; MMTS) to a final concentration of 1 mM. Aliquot, flash-freeze in liquid nitrogen, and freeze at -70°C. MMTS is a hydrophobic, thiol-reactive compound that modifies cysteines by attaching the uncharged thiomethyl-blocking group to reactive sulhydryl groups. This is a reversible reaction that arrests autoproteolysis. The activity of the enzyme can be restored to (near) unmodified levels by adding an excess of L-cysteine (~3 molar excess over MMTS). Activity Activated cathepsin K activity can be measured in 50 mM MES, 5 mM DTT, 2.5 mM EDTA, pH 5.5, and 100 µM benzyloxycarbonyl-phenylalanine-arginine-7-amido-4-methylcoumarin. Fluorescence is monitored at an excitation wavelength of ~360 nm and an emission wavelength of ~460 nm. To quantitate enzyme activity a 7-amino-4-methylcoumarin standard curve (100-5000 pmol) should be included with each assay. (Note: if MMTS was added to the enzyme after activation, the reaction buffer should also include 3 mM L-cysteine).
