IUBMB CommentsAlso acts, more slowly, on cello-oligosaccharides, lactose and D-glucosyl-1,4-beta-D-mannose. The enzyme from the white rot fungus Phanerochaete chrysosporium is unusual in having two redoxin domains, one containing a flavin and the other a protoheme group. It transfers reducing equivalents from cellobiose to two types of redox acceptor: two-electron oxidants, including redox dyes, benzoquinones, and molecular oxygen, and one-electron oxidants, including semiquinone species, iron(II) complexes, and the model acceptor cytochrome c . 2,6-Dichloroindophenol can act as acceptor in vitro.

cellobiose + acceptor = cellobiono-1,5-lactone + reduced acceptor
mechanism: cellobiose rapidly reduces the flavin group, which in turn slowly reduces the cytochrome b moiety, cytochrome b may donate electrons very rapidly to either mammalian cytochrome c or bacterial cytochrome c-551. Reactions are second-order
