What is the role of Nadph in cytochrome P450?
NADPH-cytochrome P450 reductase (CPR) plays an essential role in the cytochrome P450 enzyme system, which aids in the metabolism of endogenous and exogenous compounds including the detoxification of insecticides.
Is Nadph A reductase?
The 3 substrates of this enzyme are NADPH, H+, and oxidized hemoprotein, whereas its two products are NADP+ and reduced hemoprotein. This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH with a heme protein as acceptor….NADPH—hemoprotein reductase.

Which drug inhibits the cytochrome P450 system?
Examples of cytochrome P450 inhibitors are erythromycin, ketoconazole, diltiazem, colchicine, and the fluoroquinolones [61].
Is NADPH a cytochrome?
The systematic name of this enzyme class is NADPH:ferricytochrome-c2 oxidoreductase. Other names in common use include cytochrome c2 reductase (reduced nicotinamide adenine dinucleotide, phosphate), cytochrome c2 reductase (reduced nicotinamide adenine dinucleotide, and phosphate, NADPH).
Where is the enzyme NADPH reductase located?
NADP reductase enzyme is located on the outer side of lamella or thylakoid of the chloroplast in plants. It helps in transfer of electrons during photosynthesis from photosystem I to NADPH.
Is NADP reductase enzyme is attached to the organelle of cell?
So, the correct answer is ‘Grana thylakoids’.
What is the full name of NADPH?
nicotinamide adenine dinucleotide phosphate
NADPH (nicotinamide adenine dinucleotide phosphate) is a required cofactor for CYP-mediated biotransformation, and oxygen serves as a substrate.
Do cytochromes P450 oxidize or reduce?
Abstract. Cytochrome P450 (P450) enzymes catalyze a variety of oxidation and some reduction reactions, collectively involving thousands of substrates.
What sort of reactions do cytochrome P450 enzymes Catalyse?
Cytochrome P450 enzymes primarily catalyze mixed-function oxidation reactions, plus some reductions and rearrangements of oxygenated species, e.g. prostaglandins.
What is a cytochrome P450 inducer?
CYP enzyme inducers increase the rate of hepatic metabolism, usually through increased transcription of mRNA, and decrease serum concentrations of other drugs metabolized by the same hepatic isoenzyme.
Where is NADPH reductase enzyme located in the chloroplast?
Where does NADP reductase enzyme located in the chloroplast What is the role of this enzyme in proton gradient development?
NADP reductase enzyme is located on the outer side of the thylakoid membrane. It facilitates the breakdown of the proton gradient to release energy, which is in the form of NADPH.
What is the role of NADP reductase?
Ferredoxin: NADP+ reductase is the last enzyme in the transfer of electrons during photosynthesis from photosystem I to NADPH. The NADPH is then used as a reducing equivalent in the reactions of the Calvin cycle.
