Fig. 3From: Production of fuels and chemicals from xylose by engineered Saccharomyces cerevisiae: a review and perspectiveSchematics of the non-oxidative pentose phosphate pathway. While other intermediates can be shunted to glycolysis, sedoheptulose-7-phosphate is converted into a dead-end metabolite sedoheptulose by promiscuous phosphatase activity of Pho13p. The expression of TAL1 is indirectly regulated by PHO13. Gene nomenclature: RKI1 ribose-5-phosphate isomerase, RPE1 ribulose-5-phosphate epimerase, TKL1 transketolase, TAL1 transaldolaseBack to article page
