一般描述

溶组织梭状芽胞杆菌 是一种致病梭状芽胞杆菌,可产生粗胶原酶。这是一种含有胶原酶的混合酶,为非特异性蛋白酶和梭菌蛋白酶。[1]

应用

胶原酶可用于:[2][1][3][4][5][6]
  • 用于制备动脉组织研究晚期糖基化终产物(AGE),与其他蛋白酶一起用于分解人类肿瘤、小鼠肾脏、人脑、肺上皮细胞等多种组织。在肝脏和肾脏的灌注研究中,胰腺的消化和非实质肝细胞的分离。用于从大鼠肝脏中制备活肝细胞和从大鼠脂肪组织中分离脂肪细胞

生化/生理作用

每摩尔胶原蛋白酶被4g原子钙活化。 它被乙二醇-双(β-氨基乙基醚)-N,NN′,N′-四乙酸,β-巯基乙醇、谷胱甘肽、巯基乙酸和8-羟基喹啉抑制。
胶原酶由每mol,4g原子钙酶激活。它被乙二醇双(2-氨基乙基醚)四乙酸、β-巯基乙醇、谷胱甘肽、巯基乙酸和8-羟基喹啉所抑制。胶原酶和中性蛋白酶在组织细胞的有效释放中起着重要作用。[7]胶原酶识别序列-R-Pro-8-X-Gly-Pro-R-,其中X表示中性氨基酸。 [8]

单位定义

    The cytokines IL-17A and IL-17F have 50% amino-acid identity and bind the same receptor; however, their functional differences have remained obscure. Here we found that Il17f-/- mice resisted chemically induced colitis, but Il17a-/- mice did not, and that Il17f-/- CD45RBhiCD4+

    Hepatocytes may rupture after a drug overdose, and their intracellular contents act as damage-associated molecular patterns (DAMPs) that lead to additional leukocyte infiltration, amplifying the original injury. Necrosis-derived DNA can be recognized as a DAMP, activating liver non-parenchymal cells (NPCs).

    实验方案

    在测定胶原酶活性时,使用N-(3-[2-呋喃基]丙烯酰基)-Leu-Gly-Pro-Ala在345nm处进行连续分光光度法测定。胶原酶水解胶原肽键。

    To measure collagenase activity, N-(3-[2-Furyl]acryloyl)-Leu-Gly-Pro-Ala is used in a continuous spectrophotometric rate determination at 345 nm. Collagenase hydrolyzes collagen peptide bonds.
