Protein
D-xylonate dehydratase
Organism
Haloferax volcanii (strain ATCC 29605 / DSM 3757 / JCM 8879 / NBRC 14742 / NCIMB 2012 / VKM B-1768 / DS2)
Function
NADP-dependent D-xylose dehydrogenase involved in the degradation of D-xylose, a major component of hemicelluloses such as xylan. Catalyzes the third reaction in the xylose utilization pathway through dehydratation of D-xylonate into 2-dehydro-3-deoxy-D-xylonate.
