In molecular biology, glycoside hydrolase family 44 is a family of glycoside hydrolases.

Glycoside hydrolases EC 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(http://www.cazy.org/GH1.html) web site,[4] and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes.[5]

Glycoside hydrolase family 44 CAZY GH_44, formerly known as cellulase family J, includes enzymes with endoglucanase EC 3.2.1.4 and xyloglucanase EC 3.2.1.151 activities. Its structure consists of a TIM-like barrel domain and a beta-sandwich domain, and the active site residues are two glutamic acid residues.[6]
