An unexpectedly lichenase-stable hexasaccharide from cereal, horsetail and lichen mixed-linkage β-glucans (MLGs): Implications for MLG subunit distribution

Lichenase digestion of MLGs from three unrelated organisms yielded an unexpectedly stable hexasaccharide, β-d-Glcp-(1→3)-β-d-Glcp-(1→4)-β-d-Glcp-(1→4)-β-d-Glcp-(1→4)-β-d-Glcp-(1→3)-d-Glc (G3G4G4G4G3G), giving insights into both lichenase action and MLG sequences.
