Glucose-6-phosphate dehydrogenase (G6PD or G6PDH) (EC 1.1.1.49) is a cytosolic enzyme that catalyzes the chemical reaction D-glucose 6-phosphate + NADP+ + H2O ⇌ 6-phospho-D-glucono-1,5-lactone + NADPH + H+ This enzyme participates in the pentose phosphate pathway (see image), a metabolic pathway that supplies reducing energy to cells (such as erythrocytes) by maintaining the level of the co-enzyme nicotinamide adenine dinucleotide phosphate (NADPH).

Pyruvate kinase1
This is facilitated by glycolytic enzymes such as the M2 isoform of pyruvate kinase (PKM2) which diverts metabolites into PPP [ 6 ]. (degruyter.com)
Nucleotide1
The present study was undertaken to examine the mechanistic basis for the recent observation that the pyridine nucleotide derivative 6-aminonicotinamide (6AN, NSC 21206) enhances the accumulation and resulting cytotoxicity of cisplatin in a variety of tumor cell lines. (aspetjournals.org)
Ribose-5-phospha1
This inhibition was neither recapitulated by the knockdown of PPP enzymes, glucose 6-phosphate dehydrogenase (G6PD), or 6-phosphogluconate dehydrogenase (6PGD), nor prevented by supplementation with ribose 5-phosphate. (bvsalud.org)
Enzyme4
To explore the biochemical mechanisms which underlie these actions, we evaluated effects of 6-aminonicotinamide on ornithine decarboxylase, an enzyme involved in cellular replication and differentiation. (duke.edu)
When given to neonatal rats, 6-aminonicotinamide (10 mg/kg, i.p., on days 1, 3, 5 and 7) caused a prompt and persistent inhibition of the enzyme well in advance of adverse effects on tissue weight or on general growth. (duke.edu)
Glucose-6-phosphate dehydrogenase is also an enzyme in the Entner-Doudoroff pathway, a type of glycolysis. (wikipedia.org)
Dichloroacetate, which targets a key glycolytic pathway enzyme pyruvate dehydrogenase kinase (5, 6), has been demonstrated to inhibit tumour progression in vivo in lung and breast cancer (5, 7). (researchsquare.com)
Inhibition1
Instead, our metabolomics and metabolic phenotype studies support a mechanism in which 6-AN depletes cells of NAD(H) and impairs NAD(H)-dependent glycolytic steps resulting in inhibition of viral replication. (bvsalud.org)
Effect2
Assessment of cerebellar morphology indicated an early adverse effect of 6-AN on granule' cell division, resulting in eventual disruption of the characteristic laminar structure of this brain region. (duke.edu)
The inhibitory effect of 6-AN was rescued with precursors of the salvage pathway but not with those of other NAD+ biosynthesis pathways. (bvsalud.org)
Outcomes1
OBJECTIVE: In the absence of access to surveillance system data, single-source administrative databases are often used to study health care utilization and health outcomes among people with sickle cell disease (SCD). (cdc.gov)
Brain3
6-Aminonicotinamide (6-AN) is a nicotinic acid (vitamin B3) antagonist which, when administered to immature animals, has a profound influence on brain development. (duke.edu)
The cerebellum of the neonatal rat was chosen for study because it represents a brain region which undergoes major maturational events postnatally. (duke.edu)
These data support the view that reduced ornithine decarboxylase activity and impairment of its reactivity to growth stimuli participate in the toxic effects of 6-aminonicotinamide on brain development. (duke.edu)
