木葡聚糖（XyGs）构成高度修饰的β（1 -> 4）-葡聚糖家族，其成员在植物界中广泛且丰富。因此，XyG构成了多种植物病原微生物、腐殖微生物和肠道共生微生物的代谢可及单糖的重要储备。为了克服XyG中不同糖苷键的内在稳定性，细菌和真菌已经进化出来自多个家族的广泛的木葡聚糖活性酶库，其精细适应的三级结构最近被曝光。
The xyloglucans (XyGs) constitute a family of highly decorated beta(1 -> 4)-glucans whose members are widespread and abundant across the plant kingdom. As such, XyGs constitute a significant reserve of metabolically accessible monosaccharides for diverse phytopathogenic, saprophytic, and gut symbiotic micro-organisms. To overcome the intrinsic stability of the diverse glycosidic bonds in XyGs, bacteria and fungi have evolved extensive repertoires of xyloglucan-active enzymes from manifold families, whose exquisitely adapted tertiary structures are recently coming to light.
