In molecular biology, glycoside hydrolase family 83 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.^[2][3][4] This classification is available on the CAZy(http://www.cazy.org/GH1.html) web site,^[5] and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes.^[6]

Glycoside hydrolase family 83 CAZY GH_83 includes enzymes with neuraminidase EC 3.2.1. activity.^[7]
