以纯化的人皮肤成纤维细胞胶原酶酶原为底物,从培养的人皮肤和大鼠子宫培养基中部分纯化得到激活剂。用十二烷基硫酸钠-聚丙烯酰胺凝胶电泳对活化酶进行分析,发现这些活化剂对酶原的分子量没有可测量的变化。动力学分析表明这些活化剂的非催化作用机制,因为酶原的激活与孵育时间无关,而仅取决于活化剂组分的浓度。这些结果与这些大分子激活前胶原酶的化学计量机制一致。
Purified human skin fibroblast collagenase zymogen was used as a substrate for activators partially purified from the medium of cultured human skin and rat uterus. Analysis of the activated enzyme by sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed that these activators do not produce measurable changes in the molecular weight of the zymogen. Kinetic analysis indicated a noncatalytic mechanism of action for these activators, since zymogen activation was independent of incubation time, and dependent only upon the concentration of the activator fractions. These results are consistent with a Stoichiometric mechanism of procollagenase activation by these macromolecules.
