Description

O-Glycosyl 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 glycosyl hydrolases, based on sequence similarity, has led to the definition of 85 different families [PMID: 7624375, PMID: 8535779]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site.

Glycoside hydrolase family 26 GH26 encompasses mainly mannan endo-1,4-beta-mannosidases (EC:3.2.1.78). Mannan endo-1,4-beta-mannosidase hydrolyses mannan and galactomannan, but displays little activity towards other plant cell wall polysaccharides [PMID: 7848261]. The enzyme randomly hydrolyses 1,4-beta-D-linkages in mannans, galacto-mannans, glucomannans and galactoglucomannans.
