Let enzymes work : H 2 was produced from xylose and water in one reactor containing 13 enzymes (red). By using a novel polyphosphate xylulokinase (XK), xylose was converted into H 2 and CO 2 with approaching 100 % of the theoretical yield. The findings suggest that cell‐free biosystems could produce H 2 from biomass xylose at low cost. Xu5P=xylulose 5‐phosphate, G6P=glucose 6‐phosphate.
