Studies on Nicotinamide Adenine Dinucleotide Phosphate Reductase of Spinach Chloroplasts

open access: yesJournal of Biological Chemistry, 1972
The enzyme NADP+ reductase from spinach chloroplasts was studied by various methods of enzymology and protein chemistry. Polyacrylamide gel electrophoresis in sodium dodecyl sulfate showed the polypeptide molecular weight to be 37,000, a value which is almost exactly the same as the minimum molecular weight per FAD, so the enzyme has one FAD per ...

Identification, Heterologous Expression, and Functional Characterization of Bacillus subtilis YutF, a HAD Superfamily 5'-Nucleotidase with Broad Substrate Specificity. [PDF]

open access: yesPLoS ONE, 2016
5'-nucleotidases (EC 3.1.3.5) catalyze the hydrolytic dephosphorylation of 5'-ribonucleotides and 5'-deoxyribonucleotides as well as complex nucleotides, such as uridine 5'-diphosphoglucose (UDP-glucose), nicotinamide adenine dinucleotide and flavin ...

New Chemical Probe Targeting Bacterial NAD Kinase

open access: yesMolecules, 2020
Nicotinamide adenine dinucleotide (NAD) kinases are essential and ubiquitous enzymes involved in the tight regulation of NAD/nicotinamide adenine dinucleotide phosphate (NADP) levels in many metabolic pathways.

Fundamentals of Reductive Stress [PDF]

open access: yes
Reductive stress is a cellular insult stemming from the overgeneration of reducing equivalents and heightened antioxidant potential within the body. Maintaining redox homeostasis necessitates a delicate balance between oxidant and antioxidant production.

Is there an interplay between adherence to mediterranean diet, antioxidant status, and vascular disease in atrial fibrillation patients? [PDF]

open access: yes, 2015
Mediterranean Diet (Med-Diet) is associated with reduced incidence of vascular events (VEs) in atrial fibrillation (AF), but the mechanism accounting for its beneficial effect is only partially known.

Klf4-Sirt3/Pparα-Lcad pathway contributes to high phosphate-induced lipid degradation

open access: yesCell Communication and Signaling, 2023
Background Phosphorus commonly reduces lipid deposition in the vertebrates. However, the underlying mechanisms involved in the process remain unclear. Methods Yellow catfish were given three experimental diets with dietary phosphate levels of 3.22, 6.47 ...

Dengue complicated by acute haemolysis, methaemoglobinemia, hepatitis and rhabdomyolysis in a patient with G6PD deficiency

open access: yesSri Lanka Journal of Medicine, 2019
Glucose 6 phosphate dehydrogenase (G6PD) is a housekeeping enzyme critical in the redox metabolism. In red blood cells, it is the only source of Nicotinamide adenine dinucleotide phosphate hydrogen(NADPH) that act directly and via glutathione defends ...
