Purification and Characterization of a Novel Erythrose Reductase from Candida magnoliae
ABSTRACT Erythritol biosynthesis is catalyzed by erythrose reductase, which converts erythrose to erythritol. Erythrose reductase, however, has never been characterized in terms of amino acid… Expand

Scale-up of erythritol production by an osmophilic mutant of Candida magnoliae
Erythritol production by an osmophilic mutant of Candida magnoliae was performed in fermentations of up 50 l to develop an optimized commercial process. By simultaneous feeding glucose and yeast… Expand

  • 1 April 2005
Coenzyme Q10 (CoQ10) is a quinine consisting of ten units of the isoprenoid side-chain. Because it limits the oxidative attack of free radicals to DNA and lipids, CoQ10 has been used as an… Expand

Elevation of glucose 6-phosphate dehydrogenase activity increases xylitol production in recombinant Saccharomyces cerevisiae
To increase the NAD(P)H-dependent xylitol production in recombinant Saccharomyces cerevisiae harboring the xylose reductase gene from Pichia stipitis, the activity of glucose 6-phosphate… Expand

Molecular cloning and biochemical characterization of a novel erythrose reductase from Candida magnoliae JH110
BackgroundErythrose reductase (ER) catalyzes the final step of erythritol production, which is reducing erythrose to erythritol using NAD(P)H as a cofactor. ER has gained interest because of its… Expand

Homomeric and heteromeric interactions of the extracellular domains of death receptors and death decoy receptors.
Death receptors (DRs) can induce apoptosis by oligomerization with TRAIL, whereas death decoy receptors (DcRs) cannot, due to their lack of functional intracellular death domains. However, it is not… Expand

Amplification of 1-deoxy-d-xyluose 5-phosphate (DXP) synthase level increases coenzyme Q10 production in recombinant Escherichia coli
For the enhancement of coenzyme Q10 (CoQ10) production, 1-deoxy-d-xylulose 5-phosphate (DXP) synthase of Pseudomonas aeruginosa was constitutively coexpressed in a recombinant Escherichia coli… Expand

Screening, production and properties of a stereospecific esterase from Pseudomonas sp. S34 with high selectivity to (S)-ketoprofen ethyl ester
Abstract To isolate novel strains expressing an esterase that hydrolyzed the rac -ketoprofen ethyl ester to ( S )-ketoprofen in the stereospecific manner, we screened broad ecological niches and soil… Expand
