This oxidation may be carried out through two metabolic routes: one which is present only in fungi, and another, very similar to autotrophic nitrification, in which heterotrophic microorganisms have an ammonium-monooxygenase enzyme, and one hydroxylamine oxidoreductase
, similar to the autotrophic route, which oxidizes ammonium in a secondary manner, since these enzymes evolved to oxidize compounds such as propylene, benzene, phenol, methanol, and any other non-polar organic compound that serves as a source of carbon and energy (Bitton, 2005; Eldor, 2007).
La descarboxilasa de piruvato catalizada por la oxidorreductasa de piruvato:ferredoxina (pyruvate:ferredoxin oxidoreductase
, PFOR), produce electrones que reducen la ferredoxina, la cual a su vez, por mecanismos de catalisis, dona sus electrones a los aceptores biologicos (de electrones) o al metronidazol.
Raxone (idebenone), a synthetic short-chain benzoquinone and a cofactor for the enzyme NAD(P)H:quinone oxidoreductase
(NQO1), circumvents the complex I defect, reduces and scavenges ROS, restores cellular energy levels in retinal ganglion cells and promotes recovery of visual acuity.
Mn acts as a co-enzyme for important enzymes, oxidoreductase
, transferase, hydrolase, lyase, ligase and isomerase (Zodape, 2015).
Anticancer action of cube insecticide: correlation for rotenoid constituents between inhibition of NADH:ubiquinone oxidoreductase
and induced ornithine decarboxylase activities.
3) Studies have demonstrated that pheochromocytoma-paraganglioma syndrome is a hereditary condition frequently associated with PGs caused by germ line mutations in the SDHB, SDHC, or SDHD genes, encoding 3 of the 4 subunits of mitochondrial complex II, the succinate-ubiquinone oxidoreductase
(succinate dehydrogenase [SDH]).
In addition, the tumor suppressor gene WW domain-containing oxidoreductase
(WWOX) is a 414-amino acid protein, its WW domain mediates protein-protein interactions and is essential for the signaling pathways used by tumor suppressors to inhibit tumor growth.
vulgaris blocked UVB-induced reactive oxygen species and lactate dehydrogenase, and dose-dependently yielded increases in glutathione, NAD(P) H: quinone oxidoreductase
1, and heme oxygenase-1.
Effect of Silymarin extract administration and g-irradiation exposure on the activities of serum enzymes (ALT, AST, ALP and GGT), hepatic MDA and xanthine oxidoreductase
system (XO and XDH) and hepatic GSH and the activities of SOD and CAT.
Several studies in bacteria have reported the presence of oxalate-metabolizing proteins such as Oxalate antiport transport protein (OxIT), Formyl CoA transferase (FRC) Oxalate decarboxylase (OXDC), oxalyl CoA decarboxylase (OXC) and oxalate oxidoreductase
(XOR) is part of a group of enzymes known as the molybdenum iron-sulfur flavin hydroxylases; it is an evolutionarily conserved housekeeping enzyme, with a principal role in purine catabolism by catalyzing the two last steps in purine catabolism, forming uric acid from hypoxanthine and xanthine.
Tan was able to activate Nrf2 and increase the expression levels of Nrf2 target genes, including glutamate-cysteine ligase catalytic subunit (GCLC), NAD(P)H:quinine oxidoreductase
1 (NQO1) and hemeoxygenase-1 (HO-1), in a dose-dependent manner in HepG2 cells.
