Glycoside hydrolases {{EC number|3.2.1.}} are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A classification system for glycoside hydrolases, based on sequence similarity, has led to the definition of >100 different families.[1][2][3] This classification is available on the CAZy web site,[4][5] and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes.[6][7]Glycoside hydrolase family 49 is a family of dextranases and isopullulanases. Dextranase hydrolyses alpha-1,6-glycosidic bonds in dextran polymers.
