一般說明

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。

應用

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。

生化/生理作用

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。
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。

單位定義

一个胶原蛋白消化单元(CDU)从牛跟腱胶原蛋白中释放的肽链量和1.0 μ亮氨酸,5小时,pH7.4,37℃,在钙离子存在下的茚三酮颜色相同。一个 FALGPA水解单元每分钟,25℃,水解1.0 μmole 呋喃基丙烯酰-Leu-Gly-Pro-Ala。一个中性蛋白酶单元水解酪蛋白,产生颜色和1.0 μmole 酪氨酸每5小时,pH7.5,37℃下产生的相同。一个梭菌蛋白酶单元在DTT存在下,pH7.6,25℃,每分钟水解1.0 μmole BAEE。

分析報告

还含有梭菌蛋白酶,非特异性中性蛋白酶和胰蛋白酶活性。
