Biochem/physiol Actions
弹性蛋白酶水解弹性蛋白（弹性纤维的特定蛋白质）并消化血红蛋白、酪蛋白和纤维蛋白。
降低弹性蛋白的酶，弹性蛋白是参与拉伸过程的组织的基质成分。它是一种具有广泛特异性的丝氨酸蛋白酶。它切割小疏水性氨基酸（如 Ile、Gly、Ala、Ser、Val 和 Leu）的羧基侧的蛋白质。该酶还水解酰胺和酯，例如 N-苯甲酰基-L-丙氨酸甲酯。
General description
弹性蛋白酶是 240 个氨基酸残基的单一多肽链，含有四个二硫键。分子量约为 25.9kDa。该酶被合成为无活性的酶原，原弹性蛋白酶，其通过胰蛋白酶在 N-末端的有限蛋白水解而转化为活性形式。

The induction of cyclic GMP formation in target tissues, i.e. vascular smooth muscle and endothelial cells, by atrial natriuretic factor is followed by its egression into plasma and urine. Since the extracellular appearance of this cyclic nucleotide is used as

Defects in efficient endothelial healing have been associated with complication of atherosclerosis such as post-angioplasty neoatherosclerosis and plaque erosion leading to thrombus formation. However, current preventive strategies do not consider re-endothelialization in their design. Here, we investigate mechanisms linking immune

Decidual macrophages secrete proteases that activate protease-activated receptor 1 (PAR-1). We hypothesized that activation of the inflammatory response by bacteria is amplified by proteases, initiating labor. In addition, we hypothesized that commensal bacteria trigger an inflammatory response by activating NF-κB
