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 A + D-cellobiose = AH2 + D-cellobiono-1,5-lactone. CC -!- Also acts, more slowly, on cello-oligosaccharides, lactose and CC D-glucosyl-1,4-beta-D-mannose. 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, iron(II) complexes, and the model CC acceptor cytochrome c. CC -!- 2,6-dichloroindophenol can act as acceptor in vitro. CC -!- Formerly EC 1.1.3.25. DR Q01738, CDH_PHACH ; //
