  • 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)
  • effector
  • The first is that the binding of the terminal phospholipids alters the conformation of the active sites, implying that the tunnel acts as an effector, only allowing the enzyme to be active in certain areas of the cell. (wikipedia.org)
  • A number of proteins indicate interactions with an as yet unknown host, as indicated by the presence of predicted cell host remodeling enzymes, effector enzymes, hemolysin-like proteins, adhesins, NO reductase, and both type III and type VI secretory complexes. (biomedcentral.com)
  • pathways
  • in the degradative pathways of 2-aminobenzenesulphonic, benzenesulphonic and 4-toluenesulphonic acids in Alcaligenes sp. (wikipedia.org)
  • Annotation described in this paper also reveals evidence for several metabolic pathways that have yet to be observed experimentally, including a sulphur oxidation ( sox FCDYZAXB) gene cluster, Calvin cycle enzymes, and proteins involved in nitrogen fixation in other species (including RubisCo, ribulose-phosphate 3-epimerase, and nif gene families, respectively).

  • species
  • Structurally, the enzyme is a domain-swapped dimer in many species, although the two subunits have merged into a monomer in yeast, through gene duplication. (wikipedia.org)
  • 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)
  • iron
  • The active site of catechol dioxygenases most frequently contains iron, but manganese-containing forms are also known. (wikipedia.org)
  • Iron-containing dioxygenases can be subdivided into three classes on the basis of how iron is incorporated into the active site: those employing a mononuclear iron center, those containing a Rieske [2Fe-2S] cluster, and those utilizing a heme prosthetic group. (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)
  • Two important groups of mononuclear, non-heme iron dioxygenases are catechol dioxygenases and 2-oxoglutarate (2OG)-dependent dioxygenases. (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)
  • detoxification
  • The principal physiological function of glyoxalase I is the detoxification of methylglyoxal, a reactive 2-oxoaldehyde that is cytostatic at low concentrations and cytotoxic at millimolar concentrations. (wikipedia.org)
  • molecules
  • On an evolutionary scale, they are some of the oldest molecules known, originating in the neighborhood of 3 BY ago. (bris.ac.uk)
  • cell
  • Due to the evolutionary loss of genes coding for various lignocellulolytic enzymes (including several cellulases), P. placenta employs hemicellulolytic glycoside hydrolases and Fenton's reactions for the rapid depolymerization of plant cell wall components. (ijbs.com)
  • proteins
  • Annotation described in this paper also reveals evidence for several metabolic pathways that have yet to be observed experimentally, including a sulphur oxidation ( sox FCDYZAXB) gene cluster, Calvin cycle enzymes, and proteins involved in nitrogen fixation in other species (including RubisCo, ribulose-phosphate 3-epimerase, and nif gene families, respectively).

  • phenolic
  • 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)
  • 1,2-CTD degrades phenolic hydrocarbons key to the synthesis lipid membranes. (wikipedia.org)
  • Therefore, 1,2-CTD may bind to the cell lipid membrane via its terminal phospholipids and thus have greater access to the phenolic hydrocarbons vital in lipid membrane structure. (wikipedia.org)
  • known
  • On an evolutionary scale, they are some of the oldest molecules known, originating in the neighborhood of 3 BY ago. (bris.ac.uk)
