| physiological function | Coprinopsis cinerea fruiting bodies produce three glucanases. The endo-1,3-beta-glucanase hydrolyzes internal glycosidic bonds of laminarin to generate 1,3-beta-oligosaccharides of various lengths, the exo-1,3-beta-glucanase cleaves the longer-chain laminarioligosaccharides into short-chain disaccharides, laminaribiose and gentiobiose, and the 1,3-beta-glucosidase further hydrolyzes laminaribiose to glucose | Coprinopsis cinerea |
