show Brenda entry
EC number
1.1.99.18
Accepted name
cellobiose dehydrogenase (acceptor)
Reaction
cellobiose + acceptor = cellobiono-1,5-lactone + reduced acceptor
Other name(s)
cellobiose dehydrogenase, cellobiose oxidoreductase, Phanerochaete chrysosporium cellobiose oxidoreductase, CBOR, cellobiose oxidase, cellobiose:oxygen 1-oxidoreductase, CDH, cellobiose:(acceptor) 1-oxidoreductase
Systematic name
cellobiose:acceptor 1-oxidoreductase
CAS registry number
54576-85-1
Comment
Also acts, more slowly, on cello-oligosaccharides, lactose and D-glucosyl-1,4-β-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 [9]. 2,6-Dichloroindophenol can act as acceptor in vitro.
