About: Patatin

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

Patatin is a family of glycoproteins found in potatoes (Solanum tuberosum) and is also known as tuberin as it is commonly found within vacuoles of parenchyma tissue in the tuber of the plant. They consist of about 366 amino acids all making up and isoelectric point of 4.9. They have a molecular weight ranging from 40 to 45 kDa, but are commonly found as a 80kDa dimer. The main function of patatin is as a storage protein but it also has lipase activity and can cleave fatty acids from membrane lipids. The patatin protein makes up about 40% of the soluble protein in potato tubers. Members of this protein family have also been found in animals.

Property Value
dbo:abstract
  • La patatine est une glycoprotéine que l'on trouve dans les pommes de terre (Solanum tuberosum). La principale fonction de la patatine est d'être une protéine de stockage mais elle a aussi une activité de lipase et peut cliver les acides gras des lipides membranaires. La patatine représente environ 40 % des protéines solubles des tubercules de pomme de terre. Des membres de cette famille de protéines se rencontrent aussi chez les animaux. (fr)
