• enzymology
  • In enzymology, a NADH peroxidase (EC 1.11.1.1) is an enzyme that catalyzes the chemical reaction NADH + H+ + H2O2 ⇌ {\displaystyle \rightleftharpoons } NAD+ + 2 H2O The presumed function of NADH peroxidase is to inactivate H2O2 generated within the cell, for example by glycerol-3-phosphate oxidase during glycerol metabolism or dismutation of superoxide, before the H2O2 causes damage to essential cellular components.

  • H2O2
  • Flavonoid- peroxidase reaction as a detoxification mechanism of plants against H2O2. (wordnik.com)
  • At suboptimal H2O2 concentrations and concentrations of NADH that are saturating, NADH inhibits the peroxidase activity of the NADH peroxidase by converting the enzyme to an unstable intermediate. (wikipedia.org)
  • The actual function of NADH peroxidases and oxidases in plants is still unclear, but they could act in early signaling of oxidative stress through producing H2O2. (wikipedia.org)
  • An alternative role may include regulation of H2O2 formation by NADH peroxidase and oxidase in cell wall loosening and reconstruction. (wikipedia.org)
  • This enzyme catalyses the following chemical reaction (1) Reactive Black 5 + H2O2 ⇌ {\displaystyle \rightleftharpoons } oxidized Reactive Black 5 + 2 H2O (2) donor + H2O2 ⇌ {\displaystyle \rightleftharpoons } oxidized donor + 2 H2O Versatile peroxidase is a hemoprotein. (wikipedia.org)
  • This enzyme catalyses the following chemical reaction RH + HBr + H2O2 ⇌ {\displaystyle \rightleftharpoons } RBr + 2 H2O Bromo peroxidases of red and brown marine algae (Rhodophyta and Phaeophyta) contain vanadate. (wikipedia.org)
  • inhibit
  • Since progesterone was found to inhibit peroxidase induction due to both estrone and diethylstilbestrol, as well as estradiol, it is considered unlikely that this antagonism relates to progestin-induced increases in uterine 17 β -hydroxysteroid dehydrogenase. (springer.com)
