• In enzymology, a galactinol-raffinose galactosyltransferase (EC 2.4.1.67) is an enzyme that catalyzes the chemical reaction alpha-D-galactosyl-(1→3)-1D-myo-inositol + raffinose ⇌ {\displaystyle \rightleftharpoons } myo-inositol + stachyose Thus, the two substrates of this enzyme are α-D-galactosyl-(1→3)-1D-myo-inositol and raffinose, whereas its two products are myo-inositol and stachyose.

  • The systematic name of this enzyme class is alpha-D-galactosyl-(1→3)-myo-inositol:raffinose galactosyltransferase. (wikipedia.org)
  • Other names in common use include galactinol-raffinose galactosyltransferase, and stachyose synthetase. (wikipedia.org)
  • The main key to this is the production of high levels of protective sugars called RFOs (raffinose family oligosaccharides). (clariant.com)
  • Raffinose family oligosaccharides (RFOs) are implicated in plant regulatory mechanisms of abiotic stresses tolerance and, despite their antinutritional proprieties in grain legumes, little information is available about the enzymes involved in RFO metabolism in Fabaceae species. (bvsalud.org)
  • Galactinol synthase (GolS) is a key biological catalyst for the synthesis of the raffinose oligosaccharides (RFOs) which play important roles in abiotic stress adaptation of plants, especially drought tolerance. (ac.vn)
  • Over-expression of α-galactosidase in pea seeds to reduce raffinose oligosaccharide content Abstract The raffinose family of oligosaccharides (RFO) is a series of complex carbohydrates stored in seeds of many plant families, especially in legumes. (rochfortgeneconsulting.com)
  • Down-regulation of galactinol synthase in oilseed Brassica napus leads to significant reduction of antinutritional oligosaccharides Abstract The utility of defatted seed meal from many crops such as canola (Brassica napus L.) is limited by the presence of antinutritional factors, including sucrose galactosides, raffinose, and stachyose.

  • In the present study, the systematic survey of legume proteins belonging to five key enzymes involved in the metabolism of RFOs (galactinol synthase, raffinose synthase, stachyose synthase, alpha-galactosidase, and beta-fructofuranosidase) identified 28 coding-genes in Arachis duranensis and 31 in A. ipaënsis.

  • Genetic variation of VIT_17s0000g08960 coding for a raffinose synthase was further investigated by resequencing the gene of 85 individuals since a SNP located in the region (chr17_10,497,222_C_T) was significantly associated with stomatal conductance. (biomedcentral.com)
  • Based on the expression profiling of these genes under water deficit treatments, a galactinol synthase candidate gene (AdGolS3) was identified in A. duranensis. (bvsalud.org)

  • Transgenic Arabidopsis plants overexpressing AdGolS3 exhibited increased levels of raffinose and reduced stress symptoms under drought, osmotic, and salt stresses. (bvsalud.org)
  • Galactinol Advanced boosts the expression of genes known to have a role in oxidative stress defense and DNA repair processes. (clariant.com)
  • By helping the skin to counteract UV exposure and the effects of climatic stress, Galactinol Advanced alleviates the early signs of aging. (clariant.com)
  • Inspired by the capacity of resurrection plants to resist extremely harsh environments, Galactinol Advanced is a biomimetic active ingredient that activates the skin's defense mechanisms to improve its resilience towards environmental stress and quickly changing climate. (clariant.com)
  • Even though we were able to highlight some metabolites, e.g. , hydroxyproline, galactinol, and unsaturated fatty acid, explaining specific differential physiological (MI) responses in peanut seedlings, overall our data suggested general stress responses rather than adaptive mechanisms to heat.
