摘要
纤维素酶是一类具有多组分的复杂酶系。其多型性体现在酶系组分、酶蛋白的结构形式、理化性质以及催化机理等方面。造成纤维素酶多型性的原因包括结构基因的不同和翻译后加工的差异。另外,酶分子的表观多型性也是原因之一。文章主要对纤维素酶多型性的表现形式和可能的原因进行了分析。
Cellulase system contains a series of complex components. The polymorphism of cellulase exhibits in many aspects, such as the different components of the enzyme system, the physiological and chemical properties, the structure of enzyme protein and the catalyzing principles. The variety of different structural gene may be the principal reasons for the polymorphism of cellulases, and the processing of post-translation for proteins can cause the cellulases to be polymorphic directly. The cellulase molecules can also reveal apparent polymorphism. In this paper, the phenomena of cellulase diversity and its possible reasons have been discussed.
