Staying faithful: Xylose reductases (XRs) are highly promiscuous enzymes and are of great interest for the biosynthesis of xylitola very desirable sugar substitute. However, the expensive purification of the substrate D-xylose from the impurity L-arabinose plagues the industrial implementation of XRs....
The enzymatic conversion of d-xylose into xylitol by the immobilized cells of Candida pelliculosa (NADP + dependent xylose reductase) coupled with the immobilized cells of Methanobacterium sp. HU (hydrogenase and F 120-NADP + oxidoreductase) was done using hydrogen as an electron donor of NADP...
Xylose reductase couples NADPH to reduce D-xylose to xylitol, which is then oxidized to D-xylulose by xylitol dehydrogenase and NAD + . Once D-xylulose is formed, this intermediate flows through Pentoshunt and cooperates with glycolytic pathway to produce ethanol. However, the regulation of ...
Screening of an Aspergillus niger differential cDNA library, constructed by subtracting cDNA fragments of a xlnR loss-of-function mutant from wild-type cDNA fragments, resulted in the cloning of the gene encoding d -xylose reductase ( xyrA ). Northern blot analysis using an A. niger wild-type...

Even though the in vitro xylose isomerase activity was low, it was functional in vivo, as indicated by production of L-lactic acid from D-xylose in strains which had the xylose isomerase encoding gene expressed and xylose reductase and xylitol dehydrogenase encoding genes deleted. Under anaerobic ...
