Entries

When an enzyme can use either NAD+ or NADP+, the symbol NAD(P)+ is used.

EC 1.1.1.351

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.

Other name(s): bchC (gene name)

Systematic name: 3-deacetyl-3-hydroxyethylbacteriochlorophyllide-a:NAD+ oxidoreductase (bacteriochlorophyllide a-forming)

Comments: The enzyme, together with EC 1.3.7.15, chlorophyllide-a reductase, and EC 4.2.1.165, chlorophyllide-a 31-hydratase, is involved in the conversion of chlorophyllide a to bacteriochlorophyllide a. The enzymes can act in multiple orders, resulting in the formation of different intermediates, but the final product of the cumulative action of the three enzymes is always bacteriochlorophyllide a. The enzyme oxidizes a hydroxyl group on ring A, converting it to an oxo group.

EC 1.1.1.417

Accepted name: 3β-hydroxysteroid-4β-carboxylate 3-dehydrogenase (decarboxylating)

Reaction: a 3β-hydroxy-4α-methylsteroid-4β-carboxylate + NAD(P)+ = a 4α-methyl-3-oxosteroid + NAD(P)H + CO2 + H+

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.

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.

Reaction: xylitol + NADP+ = D-xylose + NADPH + H+

Other name(s): XYL1 (gene name, ambiguous); xyl1 (gene name, ambiguous); xyrA (gene name); xyrB (gene name)

Systematic name: xylitol:NADP+ 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 (e.g. the enzymes from Saccharomyces cerevisiae, Aspergillus niger, Trichoderma reesei, Candida tropicalis, Saitozyma flava, and Candida intermedia). 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]). Very rarely the enzyme prefers NADH (cf. EC 1.1.1.430, D-xylose reductase (NADH)).
