Intramitochondrial Localization of the Nicotinamide Adenine Dinucleotide- and Nicotinamide Adenine Dinucleotide Phosphate-dependent Xylitol Dehydrogenases

open access: yesJournal of Biological Chemistry, 1968
Abstract The two mitochondrial xylitol dehydrogenases of guinea pig liver have been studied with a view to determining their intramitochondrial locations. By procedures involving swelling, shrinking, and sonic oscillation of the particles, followed by centrifugation in a discontinuous sucrose gradient, preparations representing solubilized enzymes ...

Advanced oxidation protein products induce pre‐osteoblast apoptosis through a nicotinamide adenine dinucleotide phosphate oxidase‐dependent, mitogen‐activated protein kinases‐mediated intrinsic apoptosis pathway

open access: yesAging Cell, 2018
Osteoblast apoptosis contributes to age‐related bone loss. Advanced oxidation protein products (AOPPs) are recognized as the markers of oxidative stress and potent inducers of apoptosis. We have demonstrated that AOPP accumulation was correlated with age‐

Diagnosis and epidemiology of red blood cell enzyme disorders

open access: yesThalassemia Reports, 2013
The red blood cell possess an active metabolic machinery that provides the cell with energy to pump ions against electrochemical gradients, to maintain its shape, to keep hemoglobin iron in the reduced (ferrous) form, and to maintain enzyme and ...

Electrochemical Properties of Model Compounds of Nicotinamide-adenine-dinucleotide in Aqueous Solution [PDF]

open access: yes, 1971
International audienceThe reduction behavior of N1-methyl nicotinamide iodide has been studied by drop-time controlled polarography. ln highly acidic media (below pH 3) two pH dependent waves were observed (I and l') the latter having an abnormally high ...

Pyrroloquinoline quinone increases the expression and activity of Sirt1 and -3 genes in HepG2 cells. [PDF]

open access: yes, 2015
Sirtuin (Sirt) 1 and Sirt 3 are nicotinamide adenine dinucleotide ((+))-dependent protein deacetylases that are important to a number of mitochondrial-related functions; thus, identification of sirtuin activators is important. Herein, we hypothesize that

Study of mechanism of interaction of truncated isoniazid–nicotinamide adenine dinucleotide adduct against multiple enzymes of Mycobacterium tuberculosis by a computational approach

open access: yesInternational Journal of Mycobacteriology, 2015
Objective/Background: Isoniazid (INH) is one of the effective antituberculosis (TB) drugs used for TB treatment. However, most of the drug-resistant Mycobacterium tuberculosis (MTB) clinical strains are resistant to INH, a first-line antituberculous drug.

Insight into an Oxidative DNA-Cleaving DNAzyme: Multiple Cofactors, the Catalytic Core Map and a Highly Efficient Variant

open access: yesiScience, 2020
Summary: An oxidative DNA-cleaving DNAzyme (PL) employs a double-cofactor model “X/Cu2+” for catalysis. Herein, we verified that reduced nicotinamide adenine dinucleotide (NADH), flavin mononucleotide, cysteine, dithiothreitol, catechol, resorcinol ...
