Biochem/physiol Actions
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。
组织溶梭菌胶原酶（CCH）是一种作用于胶原蛋白的消化酶。它可用于治疗一种纤维增生性疾病Dupuytren′挛缩。
General description
组织溶梭菌胶原酶（CCH）分为两种类型：I型和II型。两者都是单一多肽，分子量分别为114kDa-113kDa。CCH I包含串联结构域，CCH II则包含单一的胶原蛋白结合结构域。
Analysis Note
还含有梭菌蛋白酶，非特异性中性蛋白酶和胰蛋白酶活性。
Application
利用组织分解梭状芽胞杆菌的胶原酶，研究了致龋细菌变形链球菌对胶原的降解作用。还利用组织分解梭状芽胞杆菌的胶原酶，研究胶原酶存在下胶原微网的存活率。
胶原酶也被用于动脉组织的制备，用于晚期糖基化终产物的研究。该酶还与其他蛋白酶一起被用于分解人类肿瘤、小鼠肾脏、人脑和肺上皮组织等。它在肝、肾灌注研究、胰腺消化、非实质肝细胞分离等方面也很有效。该产品已用于消化帕金森病患者前臂活检皮肤，以培养人类皮肤成纤维细胞原代培养物。Sigma的酶已可用于啮齿动物胰岛分离的研究中，该研究测定了葡萄糖激酶的功能。

It was reported previously that isolated human islets from individuals with type 2 diabetes mellitus (T2DM) show reduced glucose-stimulated insulin release. To assess the possibility that impaired bioenergetics may contribute to this defect, glucose-stimulated respiration (Vo(2)), glucose usage and oxidation
