ID 1.1.99.18 DE Cellobiose dehydrogenase (acceptor). AN CBOR. AN CDH. AN Cellobiose dehydrogenase. AN Cellobiose dehydrogenase (quinone). AN Cellobiose oxidase. AN Cellobiose oxidoreductase. AN Cellobiose-quinone oxidoreductase. CA Cellobiose + acceptor = cellobiono-1,5-lactone + reduced acceptor. CF FAD; Heme. CC -!- 2,6-dichloroindophenol can act as acceptor. CC -!- Also acts, more slowly, on cello-oligosaccharides, lactose and CC D-glucosyl-1,4-beta-D-mannose. CC -!- Includes EC 1.1.5.1, which is now known to be a proteolytic product CC of this enzyme. CC -!- The enzyme from the white rot fungus Phanerochaete chrysosporium is CC unusual in having two redoxin domains, one containing a flavin and CC the other a protoheme group. CC -!- It transfers reducing equivalents from cellobiose to two types of CC redox acceptor: two-electron oxidants, including redox dyes, CC benzoquinones and molecular oxygen and one-electron oxidants, CC including semiquinone species, Fe(2+) complexes and the model CC acceptor cytochrome c.
