  • extradiol
  • Extradiol members utilize ferrous iron as the active redox state, and this center is commonly coordinated octahedrally through a 2-His-1-Glu motif with labile water ligands occupying empty positions. (wikipedia.org)
  • cofactor
  • 1,2-CTD uses Fe3+ as a cofactor to cleave the carbon-carbon bond between the phenolic hydroxyl groups of catechol, thus yielding muconic acid as its product. (wikipedia.org)
  • In contrast, 2,3-CTD utilizes Fe2+ as a cofactor to cleave the carbon-carbon bond adjacent to the phenolic hydroxyl groups of catechol, thus yielding 2-hydroxymuconaldehye as its product. (wikipedia.org)
  • protein
  • Heat shock increases expression of NAD(P)H:quinone oxidoreductase (NQ01), mediator of beta-lapachone cytotoxicity, by increasing NQ01 gene activity and via Hsp70-mediated stabilisation of NQ01 protein. (thefreedictionary.com)
  • carbon
  • The second catechol hydroxyl group on carbon 3 (C3) is coordinated to Fe3+ after its deprotonation by the Tyr200 ligand. (wikipedia.org)
  • HO 2 ) residue to arachidonic acid (i.e. 5 Z ,8 Z ,11 Z ,14 Z -eicosatetraenoic acid) at carbon 5 of its 1,4 diene group (i.e. its 5 Z ,8 Z double bonds) to form 5 (S) -hydroperoxy-6 E ,8 Z ,11 Z ,14 Z -eicosatetraenoic acid (i.e. 5 S -HpETE). (wikipedia.org)
  • Collectively these fungi are major inhabitants of forest biomass thus, playing a major role in carbon cycling and recycling of nutrients [ 1 , 2 ]. (ijbs.com)
  • iron
  • The active site of catechol dioxygenases most frequently contains iron, but manganese-containing forms are also known. (wikipedia.org)
  • Most mononculear iron dioxygenases are members of the cupin superfamily in which the overall domain structure is described as a six-stranded β-barrel fold (or jelly roll motif). (wikipedia.org)
  • At the center this barrel structure is a metal ion, most commonly ferrous iron, whose coordination environment is frequently provided by residues in two partially conserved structural motifs: G(X)5HXH(X)3-4E(X)6G and G(X)5-7PXG(X)2H(X)3N. (wikipedia.org)
  • In the 2OG-dependent dioxygenases, ferrous iron (Fe(II)) is also coordinated by a (His)2(Glu/Asp)1 "facial triad" motif. (wikipedia.org)
  • group
  • This list contains a list of EC numbers for the first group, EC 1, oxidoreductases, placed in numerical order as determined by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology. (wikipedia.org)
  • phenolic compound
  • More particularly, the systems taught here include a phenolic compound bound to a reactive oxygen species, wherein the phenolic compound and the reactive oxygen species react at a target area in the presence of an oxidoreductase enzyme. (patentsencyclopedia.com)
  • 2. The method of claim 1, wherein the phenolic compound component comprises a hydrolysable tannin, a condensed tannin, or a combination thereof. (patentsencyclopedia.com)
  • 3. The method of claim 1, wherein the phenolic compound component comprises a flavanol. (patentsencyclopedia.com)
