From: Exploring d-xylose oxidation in Saccharomyces cerevisiae through the Weimberg pathway
A condensed metabolic map describing d-xylose oxidation via the Weimberg pathway. Five enzymatic reactions convert d-xylose to α-ketoglutarate that enter the central cellular metabolism via the TCA cycle. For comparison, the oxido-reduction of d-xylose to d-xylulose through the oxido-reduction pathway (XR/XDH) is also shown. Required cofactors (ATP, NADH or NADPH) are indicated for the two xylose pathways while the central cellular metabolism is presented in a simplified scheme. XR xylose reductase, XDH xylitol dehydrogenase, XK xylulose kinase, TCA cycle tricarboxylic acid cycle
