  2. Xenobiotic metabolism - Wikipedia

    en.wikipedia.org/wiki/Xenobiotic_metabolism

    Xenobiotic metabolism is divided into three phases. In phase I, enzymes such as cytochrome P450 oxidases introduce reactive or polar groups into xenobiotics. These modified compounds are then conjugated to polar compounds in phase II reactions. These reactions are catalysed by transferase enzymes such as glutathione S-transferases.

  3. Drug metabolism - Wikipedia

    en.wikipedia.org/wiki/Drug_metabolism

    Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...

  4. NAD (P)H dehydrogenase, quinone 2 - Wikipedia

    en.wikipedia.org/wiki/NAD(P)H_dehydrogenase...

    It is a phase II detoxification enzyme which can carry out two or four electron reductions of quinones. Its mechanism of reduction is through a ping-pong mechanism involving its FAD cofactor. Initially in a reductive phase NQO2 binds to reduced dihydronicotinamide riboside (NRH) electron donor, and mediates a hydride transfer from NRH to FAD.

  5. Detoxification - Wikipedia

    en.wikipedia.org/wiki/Detoxification

    The liver and kidney are naturally capable of detox, as are intracellular (specifically, inner membrane of mitochondria or in the endoplasmic reticulum of cells) proteins such as CYP enzymes. In cases of kidney failure , the action of the kidneys is mimicked by dialysis ; kidney and liver transplants are also used for kidney and liver failure ...

  6. Glutathione S-transferase - Wikipedia

    en.wikipedia.org/wiki/Glutathione_S-transferase

    Glutathione S-transferases (GSTs), previously known as ligandins, are a family of eukaryotic and prokaryotic phase II metabolic isozymes best known for their ability to catalyze the conjugation of the reduced form of glutathione (GSH) to xenobiotic substrates for the purpose of detoxification.

  8. NAD(P)H dehydrogenase (quinone 1) - Wikipedia

    en.wikipedia.org/wiki/NAD(P)H_dehydrogenase...

    NAD(P)H dehydrogenase [quinone] 1 is an enzyme that in humans is encoded by the NQO1 gene. [5] This protein-coding gene is a member of the NAD(P)H dehydrogenase (quinone) family and encodes a 2-electron reductase (enzyme).

  9. Glyoxalase system - Wikipedia

    en.wikipedia.org/wiki/Glyoxalase_system

    [1] [2] This system has been studied in both bacteria and eukaryotes. [ 2 ] [ 3 ] [ 4 ] This detoxification is accomplished by the sequential action of two thiol-dependent enzymes; firstly glyoxalase І , which catalyzes the isomerization of the spontaneously formed hemithioacetal adduct between glutathione and 2-oxoaldehydes (such as ...
