Fig. 4From: Lytic polysaccharide monooxygenases from Myceliophthora thermophila C1 differ in substrate preference and reducing agent specificityStructural classification of reducing agents into five groups. Group I, monophenols. Group II, ortho-, meta- or para-isomers of compounds bearing a benzenediol moiety. Group III, reducing agents with a 1,2,3-benzenetriol moiety. Group IV, sulfur-containing compounds. Group V, compounds with neither a phenolic ring nor a sulfur atomBack to article page
