   3.2.1.6 | 1,3-1,4-beta-D-glucan + H2O |
LamR cleaves the 1,4-beta-linkages of 3-O-substituted beta-glucose in beta-glucans such as lichenin and 1,3-1,4-beta-glucan from the cell walls of barley endosperm, analysis of reaction products |

| 3.2.1.6 | 1,3-1,4-beta-D-glucan + H2O |
soluble, from barley, endo-acting enzyme, preference for mixed-link 1,3-1,4-beta-D-glucan substrates, highest catalytic efficiency with barley 1,3-1,4-beta-D-glucan |
Rasamsonia emersonii |
cellooligosaccharide |
spectrum of oligosaccharide products by EG VI and EG VII including linear beta-1,4-gluco and mixed-link oligosaccharides, relative distribution of the cellooligosaccharides DP 1-5 after 24 h incubation |

substrate can make a nucleophilic attack upon itself, the major product being a cyclic beta-1,3-heptaglucan. NMR confirms uniquely beta-1,3-linkages and no reducing end. The cyclic laminariheptaose molecule is not completely planar and torsion angles at the glycosidic linkages fluctuate between two energy minima |
