Cyanobacterial NADPH dehydrogenase complexes

Photosynthesis Research, 2007
Cyanobacteria possess functionally distinct multiple NADPH dehydrogenase (NDH-1) complexes that are essential to CO(2) uptake, photosystem-1 cyclic electron transport and respiration. The unique nature of cyanobacterial NDH-1 complexes is the presence of subunits involved in CO(2) uptake.

Development of an NADPH-Dependent Homophenylalanine Dehydrogenase by Protein Engineering

ACS Synthetic Biology, 2013
l-Homophenylalanine is a nonproteinogenic amino acid and can be used as a versatile pharmaceutical intermediate. Production of l-homophenylalanine involves amination of the keto acid precursor 2-oxo-4-phenylbutyric acid (2-OPBA), which can be accomplished by bioenzymatic processes.

Inhibition of NADP-dependent dehydrogenases by modified products of NADPH

Archives of Biochemistry and Biophysics, 1975
Abstract When NADPH was incubated at neutral pH, a modified product which had no absorbancy at 340 nm, but exhibited a slight shoulder in the region of 280–300 nm with maximum absorbancy at 266 nm, was produced. Phosphate accelerated the conversion. This compound was tentatively designated as NADPH-X.

NADPH Dehydrogenase Activity of p67^PHOX, a Cytosolic Subunit of the Leukocyte NADPH Oxidase

Biochemistry, 1999
The leukocyte NADPH oxidase catalyzes the one-electron reduction of oxygen to O2- at the expense of NADPH. It is a multicomponent enzyme comprising a membrane-bound flavocytochrome (cytochrome b558) and at least four cytosolic components: p47PHOX, p67PHOX, p40PHOX, and Rac, a small GTPase.

Glucose Dehydrogenase for the Regeneration of NADPH and NADH

2005
Glucose dehydrogenases (GDHs) occur in several organisms such as Bacillus megaterium and Bacillus subtilis. They accept both NAD+ and NADP+ as cofactor and can be used for the regeneration of NADH and NADPH. In order to demonstrate their applicability we coupled an NADP+-dependent, (R)-specific alcohol dehydrogenase (ADH) from Lactobacillus kefir with ...

Coupling of 6‐phosphogluconate dehydrogenase with NADPH oxidase in neutrophils: Nox2 activity regulation by NADPH availability

The FASEB Journal, 2011
ABSTRACT It is well known that activation of the phagocyte NADPH oxidase requires the association of cytosolic proteins (p67‐phox, p47‐phox, p40‐phox, and Rac) with the membrane cytochrome b 558 , leading ...

Regulation of pentose phosphate pathway dehydrogenases by NADP+/NADPH ratios

Biochemical and Biophysical Research Communications, 1976
Abstract Equilibrium dialysis indicates that rat liver glucose-6-P dehydrogenase binds two molecules of NADP + per subunit with a dissociation constant of 0.6 × 10 −6 M. The NADP + free enzyme will not bind glucose-6-P indicating a compulsory order of substrate binding. Development of an isotopic assay allowed a direct measurement of the effect of

NADPH-forming dehydrogenases in the adipose tissue of obese and nonobese diabetics

Metabolism, 1976
The activity of glucose-6-phosphate dehydrogenase (EC 1.1.1.49) of adipose tissue was markedly decreased, both on a protein and on a fat cell number basis, in nonobese diabetics compared to control subjects, but was unchanged in obese diabetics. Average value in the obese diabetics was about fourfold higher than in nonobese diabetics. On the other hand,

The roles of NADPH and isocitrate dehydrogenase in cochlear mitochondrial antioxidant defense and aging

Hearing Research, 2023
Hearing loss is the third most prevalent chronic health condition affecting older adults. Age-related hearing loss affects one in three adults over 65 years of age and is caused by both extrinsic and intrinsic factors, including genetics, aging, and exposure to noise and toxins.

Enzymic analysis of NADPH metabolism in β-lactam-producing Penicillium chrysogenum: Presence of a mitochondrial NADPH dehydrogenase

Metabolic Engineering, 2006
Based on assumed reaction network structures, NADPH availability has been proposed to be a key constraint in beta-lactam production by Penicillium chrysogenum. In this study, NADPH metabolism was investigated in glucose-limited chemostat cultures of an industrial P. chrysogenum strain.
