谷物中蛋白类木聚糖酶抑制剂研究进展

近年来研究发现谷物中存在能抑制木聚糖酶活性的蛋白质,降低了木聚糖酶在动物生产中的应用效果。自第一种木聚糖酶抑制剂蛋白首先在小麦中被发现以来,随后发现的木聚糖酶抑制剂分别属于三种不同的类型,即TAXI型、XIP型和TLXI型。综述了三种不同类型木聚糖酶抑制剂的研究概况,为研究木聚糖酶抑制剂的作用机理,及进一步开发具有良好抗逆性的木聚糖酶提供理论基础。

Current Progress on Endoxylanase Inhibitors in Cereals

Recently, some researches suggested that cereals contain proteinaceous inhibitors of endo-xylanases, decreasing the practical effect of xylanase in animal feed industry. Since this kind of inhibitor was found firstly from wheat, a large number of endo-xylanase inhibitors have been discovered. They are mainly divided into three classes: xylanase inhibitor protein (XIP) type,Triticum aestivum xylanase inhibitor (TAXI) type and thaumatin-like xylanase inhibitor (TLXI) type. These three different types of xylanase inhibitors profiles were reviewed, and a theoretical basis for further study on inhibition mechanism of xylanase inhibitor and molecular improvement on xylanase were provided.
