Analysis Note
也具有梭菌蛋白酶、非特异性中性蛋白酶和胰蛋白酶活性。
Application
胶原酶已被用于制备动脉组织,用于研究晚期糖基化终产物(AGE)。该酶还与其他蛋白酶一起用于人肿瘤、小鼠肾、人脑、肺上皮和许多其他组织的解聚。它在肝脏和肾脏灌注研究,胰腺消化和非实质肝细胞的分离中也是有效的。
Biochem/physiol Actions
有效地从组织中释放细胞需要胶原酶和中性蛋白酶的共同作用。每摩尔酶用 4 克原子钙 (Ca2+) 激活胶原酶。一般认为培养滤液至少含有 7 种不同的蛋白酶,分子量范围为 68-130 kDa(最适用 pH:6.3-8.8)。该酶识别序列-R-Pro-8-X-Gly-Pro-R-,其中 X 是最常见的中性氨基酸。
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。

Beware of the small finger and/or the proximal interphalangeal joint? Skin lacerations following collagenase injection in dupuytren contracture.

Ask the doctor. I have Dupuytren's contracture in both hands. I've had "needle" surgery in one hand, and the fingers straightened. But they seem to want to contract again. What can I do?

Elevated interstitial fluid pressure (IFP) in a tumor is a barrier to tumor accumulation of systemic delivery of nanocarriers. In this study, we investigated whether intravenous injection of type I collagenase (collagenase-1) reduced IFP in tumors and increased the accumulation

Dupuytren's disease is a common, costly and recurrent health issue. This review compares Clostridium histolyticum collagenase with current operative treatments. Collagenase management is an effective non-surgical alternative associated with lower risks of serious adverse events, but higher incidence of non-serious

This paper summarizes the development and validation of five enzyme activity methods to assess the specific inhibition of human endogenous matrix metalloproteinases MMP-1 (interstitial collagenase), MMP-2 (gelatinase A), MMP-3 (stromelysin 1), MMP-8 (collagenase 2) and MMP-13 (collagenase 3) by anti-Collagenase
实验方案
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.
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。
