Application
Human chymase has been used in a study to assess the effects of Panax notoginseng flower extract on the TGF-β/Smad signal transduction pathway in heart remodeling. Human chymase has also been used in a study to investigate the blood glucose level and survival in streptozotocin-treated human chymase transgenic mice.
Chymase has been implicated in generation of angiotensin II and cleavage of big endothelin. Studies indicate it may be involved in vascular proliferation, myocardial infarction and dermatitis.
Actions biochimiques/physiologiques
The enzyme rapidly converts angiotensin I to angiotensin II. Optimum pH for the enzyme activity is between 7.5 and 9.0. Enzyme activity is inhibited by soybean trypsin inhibitor, phenylmethylsulfonyl fluoride and chymostatin.
Propriétés physiques
Chymase is a cathepsin G-like, S1 serine proteinase found primarily in mast cells. It has a molecular mass of ~30 kDa, however its apparent molecular mass on SDS-PAGE is around 37 kDa.
Définition de l'unité
One unit hydrolyzes one micromole of N-benzoyl-L-tyrosine ethyl ester (BTEE) per minute at pH 7.8 and 25 °C. The assay buffer used to determine the enzyme activity contains 27 mM Tris-HCl, pH 7.8, with 150 mM NaCl and 0.43 mM BTEE.
Forme physique
Supplied as a solution in 20 mM Tris, 0.8 M NaCl and 25% glycerol, pH 7.6

We previously established a mast cell (MC)-dependent thermal injury model in mice with ulceration and scar formation that depended on nonredundant functions of mouse MC protease (mMCP)4 and mMCP5. We hypothesized that MC activation is an early event and now

Mast cells have been linked to osteoporosis and bone fractures, and in a previous study we found that mice lacking a major mast cell protease, chymase, develop increased diaphyseal bone mass. These findings introduce the possibility that mast cell chymase

Mast cells (MCs) are found in large numbers in lungs of patients with pulmonary fibrosis. However, the functions of MCs in lung fibrosis remain largely unknown. We assessed the role of MCs and MC protease 4 (MCPT4), the mouse counterpart

HDL particles may enter atherosclerotic lesions having an acidic intimal fluid. Therefore, we investigated whether acidic pH would affect their structural and functional properties. For this purpose, HDL(2) and HDL(3) subfractions were incubated for various periods of time at different

A chymostatin-sensitive angiotensin II-generating enzyme was found in human gastroepiploic arteries. The enzyme was purified using heparin affinity and gel filtration columns. The molecular mass of the purified enzyme was 30 kDa, and the optimum pH was between 7.5 and
