About: Xylomannan

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Xylomannan is an antifreeze molecule, found in the freeze-tolerant Alaskan beetle Upis ceramboides. Unlike antifreeze proteins, xylomannan is not a protein. Instead, it is a combination of a sugar (saccharide) and a fatty acid that is found in cell membranes. As such is expected to work in a different manner than AFPs. It is believed to work by incorporating itself directly into the cell membrane and preventing the freezing of water molecules within the cell.

  • Le xylomannane est une molécule antigel découverte au début du XXIe siècle dans des scarabées d’Alaska tolérant le froid : (en). Contrairement aux protéines antigel, le xylomannane n’est pas une protéine. Il s’agit d’une combinaison de sucre et d’acide gras que l’on trouve dans les membranes cellulaires.Le xylomannane est aussi extrait de l’algue rouge Nothogenia fastigiata. La fraction aqueuse F6 de xylomannane sulfaté provenant de cette algue s’est avérée inhibitrice de la réplication d’une variété de virus dont l’Herpes simplex virus de type 1 et 2 (HSV-1 et HSV-2). Cette même molécule est également capable de diminuer l’adsorption du HSV sur la cellule hôte. (fr)

It is believed to work by incorporating itself directly into the cell membrane and preventing the freezing of water molecules within the cell. Xylomannan is also found in the red seaweed . Fraction F6 of a sulphated xylomannan from Nothogenia fastigiata was found to inhibit replication of a variety of viruses, including Herpes simplex virus types 1 and 2 (HSV-1, HSV-2), Human cytomegalovirus (HCMV, HHV-5), Respiratory syncytial virus (RSV), Influenzavirus A, Influenzavirus B, Junin and Tacaribe virus, Simian immunodeficiency virus, and (weakly) Human immunodeficiency virus types 1 and 2.
