1.1.1.10 | additional information | the transportation of D-xylose across the cell membrane of Chlorella sorokiniana is realized by an inducible hexose symporter. The uptake of D-xylose subsequently activates the expression of key catalytic enzymes that enables D-xylose entering central metabolism | Chlorella sorokiniana |
1.1.1.307 | metabolism | D-glucose-induced algal cells exhibit a remarkably increased D-xylose uptake rate. The uptake of D-xylose activates the related metabolic pathway, and the activities of a NAD(P)H-linked xylose reductase XR and NADP+-linked xylitol dehydrogenase XDH are detected in C. sorokiniana. Compared with the culture in the dark, the consumption of D-xylose increases 2fold under light but decreases to the same level with addition of 3-(3,4-dichlorophenyl)-1,1-dimethylurea | Chlorella sorokiniana |
