N-linked glycans of Schizophyllum commune consist of Man(5-9)GlcNAc(2) structures. Lack of further glycan maturation is explained by the absence of genes encoding such functions in this and other homobasidiomycetes. N-linked glycans in vegetative mycelium and fruiting bodies of S. commune are mainly Man(7)GlcNAc(2) and Man(5)GlcNAc(2), respectively, suggesting more efficient mannose trimming in the mushroom.
