Accepted name: phosphogluconate dehydrogenase [NAD(P)+-dependent, decarboxylating]
Reaction: 6-phospho-D-gluconate + NAD(P)+ = D-ribulose 5-phosphate + CO2 + NAD(P)H + H+
For diagram of reaction click here.
Systematic name: 6-phospho-D-gluconate:NAD(P)+ 2-oxidoreductase (decarboxylating)
Comments: The enzyme participates in the oxidative branch of the pentose phosphate pathway, whose main purpose is to produce reducing power and pentose for biosynthetic reactions. Unlike EC 1.1.1.44, phosphogluconate dehydrogenase (NADP+-dependent, decarboxylating), it is not specific for NADP+ and can accept both cofactors with similar efficiency. cf. EC 1.1.1.343, phosphogluconate dehydrogenase [NAD+-dependent, decarboxylating].

Other name(s): sdmB (gene name)
Systematic name: 3β-hydroxysteroid-4β-carboxylate:NAD(P)+ 3-oxidoreductase (decarboxylating)
Comments: This bacterial enzyme participates in the biosynthesis of bacterial sterols. Together with EC 1.14.13.246, 4β-methylsterol monooxygenase (SdmA) it forms an enzyme system that removes one methyl group from the C-4 position of 4,4-dimethylated steroid molecules. SdmA catalyses three successive oxidations of the C-4β methyl group, turning it into a carboxylate group; SdmB is a bifunctional enzyme that catalyses two different activities. As EC 1.1.1.417 it catalyses an oxidative decarboxylation that results in reduction of the 3β-hydroxy group at the C-3 carbon to an oxo group. As EC 1.1.1.270, 3β-hydroxysteroid 3-dehydrogenase, it reduces the 3-oxo group back to a 3β-hydroxyl. Since the remaining methyl group at C-4 is in an α orientation, it cannot serve as a substrate for a second round of demethylation by this system.

Comments: The substrate of this enzyme is formed as an intermediate during L-methionine salvage from S-methyl-5'-thioadenosine, which is formed during the biosynthesis of polyamines. The human enzyme also functions as a transcriptional co-regulator that downregulates the expression of many tumor-suppressor genes, thus providing a link between gene repression and the methionine salvage pathway. A similar, but NADP-specific, enzyme is involved in dimethylsulfoniopropanoate biosynthesis in algae and phytoplankton.

Accepted name: D-xylose reductase (NADH)
Reaction: xylitol + NAD+ = D-xylose + NADH + H+
Other name(s): XYL1 (gene name) (ambiguous)
Systematic name: xylitol:NAD+ oxidoreductase
Comments: Xylose reductases catalyse the reduction of xylose to xylitol, the initial reaction in the fungal D-xylose degradation pathway. Most of the enzymes exhibit a strict requirement for NADPH (cf. EC 1.1.1.431, D-xylose reductase (NADPH)). Some D-xylose reductases have dual coenzyme specificity, though they still prefer NADPH to NADH (cf. EC 1.1.1.307, D-xylose reductase [NAD(P)H]). The enzyme from Candida parapsilosis is a rare example of a xylose reductase that significantly prefers NADH, with Km and Vmax values for NADH being 10-fold lower and 10-fold higher, respectively, than for NADPH.
