Resum

1,3-1,4-β-Glucanases (or lichenases, EC 3.2.1.73) hydrolyse linear β-glucans containing β-1,3 and β-1,4 linkages such as cereal β-glucans and lichenan, with a strict cleavage specificity for β-1,4 glycosidic bonds on 3-O-substituted glucosyl residues. The bacterial enzymes are retaining glycosyl hydrolases of family 16 with a jellyroll β-sandwich fold and a substrate binding cleft composed of six subsites. The present paper reviews the structure-function aspects of the enzymatic action including mechanistic enzymology, protein engineering and X-ray crystallographic studies.
