O-Glycosyl hydrolases ( 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 glycosyl hydrolases, based on sequence similarity, has led to the definition of 85 different families [ 1 , 2 ]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) website.

Glycoside hydrolase family 32 GH32 comprises enzymes with several known activities; invertase/fructofuranosidase ( 3.2.1.26 ); inulinase ( 3.2.1.7 ); levanase ( 3.2.1.65 ); exo-inulinase ( 3.2.1.80 ); sucrose:sucrose 1-fructosyltransferase ( 2.4.1.99 ); fructan:fructan 1-fructosyltransferase ( 2.4.1.100 ).
