Folding of xylan onto cellulose fibrils in plant cell walls revealed by solid-state NMR

The polysaccharide xylan binds to cellulose microfibrils in the plant cell wall, but the nature of this interaction remains unclear. Here Simmonset al. show that while xylan forms a threefold helical screw in solution it forms a twofold screw to bind cellulose microfibrils in the plant cell wall.
