利用从小麦粉中分离的水溶性和不水溶性底物以及糖苷水解酶第10科和第11科的几种木聚糖酶，研究了阿拉伯木聚糖结构对木聚糖酶活性的影响。底物中阿拉伯糖的含量对木聚糖酶活性的影响与阿拉伯糖：木糖的比例成线性关系，并在不同程度上取决于木聚糖酶的特异性。底物的可溶/不溶特性对酶活性有很大影响，并观察到不同的选择性（对不溶性阿拉伯木聚糖的活性和对可溶性阿拉伯木聚糖的活性）。给定木聚糖酶的特异性和选择性之间没有关系。(c) 2006年化学工业学会
The effect of arabinoxylan structure on xylanase activity was investigated using a range of water-soluble and water-insoluble substrates isolated from wheat flour and several xylanases from families 10 and 11 of the glycoside hydrolases. The arabinose content of the substrates affected the activity in a linear manner related to the arabinose:xylose ratio and to different extents depending on the specificity of the xylanase. The soluble/insoluble feature of the substrates had a strong impact on the enzymatic activity and different selectivities (activity on insoluble arabinoxylan vs. activity on soluble arabinoxylan) were observed. There was no relationship between specificity and selectivity of a given xylanase. (c) 2006 Society of Chemical Industry
