  • Liu, Jin-Yuan 2006-08-30 00:00:00 A novel cDNA of phospholipid hydroperoxide glutathione peroxidase (PHGPx), which encodes a functional protein capable of complementing the yeast PHGHX-deletion mutant, was recently discovered in radish (Raphanus sativus) and designated as RsPHGPx [Yang X-D, Li W-J, Liu J-Y (2005) Biochim Biophys Acta 1728:199- (deepdyve.com)
  • novel
  • However, it is of interest to observe the genesis of novel sequences in 24 TF families and the apparent termination of 2 TF families with the emergence of Marchantia. (scoop.it)
  • Thus
  • Thus organellar Prx proteins enable an alternative water-water cycle for detoxification of photochemically produced H2O2, which acts independently from the ascorbate-dependent Asada-Halliwell-Foyer cycle. (uni-bielefeld.de)
  • species
  • The accumulation was greatly diminished using ascorbate as a scavenger or respectively diphenyleneiodonium chloride (DPI) as an inhibitor of reactive oxygen species production. (deepdyve.com)
  • Overall, TF basic functions and distribution across families appear to be conserved when compared to other plant species. (scoop.it)
  • significantly
  • The heat-induced expression levels were significantly reduced in the presence of ascorbate or DPI indicating that H2O2 is an essential component in the heat stress signalling pathway. (deepdyve.com)
  • genes
  • Significant induction of the genes tested after diamid treatment and moderate expression of the sHSP genes in the presence of 50 mM ascorbate at 37°C occurred without activation of HSF, indicating that other mechanisms may be involved in stress signalling. (deepdyve.com)
  • complex
  • The heat stress induction of a high mobility HSE-binding complex, characteristic for later phase of heat shock response, was blocked by ascorbate and DPI. (deepdyve.com)
  • H2O2 was unable to induce this complex suggesting that H2O2 is involved only in the early stages of HSF activation. (deepdyve.com)
  • structures
  • With the large amount of information currently available regarding Prx structures and sequences, family members are now recognized to fall into six classes or subgroups, designated as Prx1 (essentially synonymous with "typical 2-Cys"), Prx5, Prx6, PrxQ, Tpx and AhpE groups. (wikipedia.org)
  • cell
  • Peroxiredoxins are proposed to play a role in cell signaling by regulating H2O2 levels. (wikipedia.org)
  • members
  • Tuteja, Narendra 2015-04-12 00:00:00 Lectin receptor-like kinases (LecRLKs) are members of RLK family composed of lectin-like extracellular recognition domain, transmembrane domain and cytoplasmic kinase domain. (deepdyve.com)
  • Ultimately it was realized that the CR can reside in multiple positions in various Prx family members, leading to the addition of the "atypical 2-Cys Prx" category (Prxs for which a CR is present, but not in the "typical", originally identified position). (wikipedia.org)
