CC -!- FUNCTION: Catalyzes the single-oxidation or sequential double oxidation
CC reaction of carbohydrates primarily at carbon-2 and/or carbon-3 with
CC the concomitant reduction of the flavin. The enzyme exhibits a broad
CC sugar substrate specificity, oxidizing different aldopyranoses to the
CC corresponding C-1, C-2, C-3 or C-1,2, C-2,3 and C-3,4 (di)dehydro
CC sugars with substrate-specific regioselectivity. Accepts only a narrow
CC range of electron acceptors such as substituted benzoquinones and
CC complexed metal ions and reacts extremely slowly with O(2) as acceptor.
CC May play a role in the natural recycling of plant matter by oxidizing
CC all major monosaccharides in lignocellulose and by reducing quinone
CC compounds or reactive radical species generated during lignin
CC depolymerization (By similarity). {ECO:0000250|UniProtKB:Q3L245}.
