Since the double Deltagrx1Deltagrx2 mutant is hypersensitive to selenite we decided to evaluate mechanisms underlying this phenomenon and establish the roles of other components of yeast glutaredoxin system, in particular glutaredoxin 5 in the selenite resistance. We found elevation in

Mammalian dimeric dihydrodiol dehydrogenase (DD) is identical to NADP+-dependent D-xylose dehydrogenase. A recent investigation showed that the three-dimensional structure of monkey DD is similar to those of prokaryotic NADP(H)-dependent glucose-fructose oxidoreductase (GFO) and 1,5-anhydro-D-fructose reductase (AFR); however, it differs in

We recently identified a microbial conversion of L-ascorbic acid (AsA) to L-erythroascorbic acid (eAsA), a five-carbon analog of AsA. In this paper, we show that ubiquitin plays a crucial role in this process. Based on an assay that determined AsA
