Interaction with arginine 597 of NADPH-cytochrome P-450 oxidoreductase is a primary source of the uniform binding energy used to discriminate between NADPH and NADH

Biochemistry, 1993
Site-directed mutagenesis has been used in conjunction with pH and alternate substrate/inhibitor studies to characterize the interactions between NADPH-cytochrome P-450 oxidoreductase (P-450R) and the 2'-phosphate of NADP(H) that provide P-450R with its strong nicotinamide nucleotide specificity. It is known that the 2'-phosphate of NADP(H) is bound to

Purification and resolution of NADH diaphorase activity from NADPH diaphorase-linked: O2 oxidoreductase activity of human neutrophils

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1985
Intrinsic NADPH diaphorase activity is a component of the membrane-bound NAD(P)H:O2 oxidoreductase of human neutrophils. NADH-specific diaphorase activity is also present in membrane fractions rich in oxidoreductase activity. Studies were undertaken to determine whether the NADH diaphorase might also be intrinsic to the oxidoreductase.

Subcellular location of hypothalamic progesterone metabolizing enzymes and evidence for distinct NADH- and NADHP-linked 3α-hydroxysteroid oxidoreductase activities

Journal of Steroid Biochemistry, 1980
Abstract The subcellular location of adult female rat hypothalamic steroid 5α-reductase and 3α-hydroxysteroid oxidoreductase (3α-HSD) activities, which catalyze the conversion of progesterone to 3α-hydroxy-5α-pregnan-20-one via 5α-pregnane-3,20-dione, have been investigated using 3 H-labeled substrates and an isotopic dilution assay system. In crude

[Study of the NADH and NADPH-ferredoxin oxidoreductase activities in Clostridium acetobutylicum].

Canadian journal of microbiology, 1977
The NADH and NADPH-ferredoxin oxidoreductase have been studied in Clostridium acetobutylicum. Acetyl-CoA is an obligatory activator of NADH-ferredoxin reductase activity and NADH a competitive inhibitor of ferredoxin-NAD+ reductase activity. These regulations are the same when C.

Biochemical, Biophysical, and Mechanistic Insights on a Putative Oxidoreductase From Mycobacterium tuberculosis That Shares Structural Homology With Tetracycline Destructase

Proteins: Structure, Function, and Bioinformatics
Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis. The emergence of Mtb's multidrug‐resistant and extremely drug‐resistant strains has imposed a great challenge for TB treatment.
