physiological function
D-xylose is oxidized exclusively to the tricarboxylic acid cycle intermediate alpha-ketoglutarate, involving D-xylose dehydrogenase (HVO_B0028), a xylonate dehydratase (HVO_B0038A), 2-keto-3-deoxyxylonate dehydratase (HVO_B0027), and alpha-ketoglutarate semialdehyde dehydrogenase (HVO_B0039). An HVO_B0028 gene deletion mutant cannot grow on xylose but grows unaffected on glucose as the wild-type
physiological function
Haloferax volcanii degrades the pentoses D-xylose and L-arabinose via an oxidative pathway to 2-oxoglutarate as an intermediate. The initial dehydrogenases of the pathway, D-xylose dehydrogenase (XDH) and L-arabinose dehydrogenase (L-AraDH) catalyze the NADP+ dependent D-xylose and L-arabinose oxidation
