[Abstract]  The complement component C3 is the major effector molecule of the complement system. C3 circulates in the blood and interstitial fluids as pro-enzyme and is activated by enzymatic cleavage into a C3a portion, a classic anaphylatoxin that functions as chemoattractant and immune cell activator, and the C3b portion, the body’s most potent opsonin. C3 cleavage is in most cases mediated by an enzyme complex called the C3 convertase. However, it is now becoming increasingly clear that the cleavage of C3 by a range of ‘single’ proteases into bioactive C3a and C3b fragments is of high physiological ... [摘要]  补体组分C3是补体系统的主要效应分子。 C3作为前酶在血液和间质液中循环,并通过酶裂解活化为C3a部分,用作化学引诱物和免疫细胞活化剂的经典过敏毒素和作为机体最有效调理素的C3b部分。 C3切割在大多数情况下由称为C3转化酶的酶复合物介导。 然而,现在越来越清楚的是,通过一系列"单一"蛋白酶将C3切割成生物活性C3a和C3b片段具有高生理学意义。 在这里,我们描述了通过丝氨酸蛋白酶组织蛋白酶L酶切割人C3的方案和通过蛋白质印迹检测裂解产物C3a和C3b作为这种酶反应的实例。
