Comment(s) |
- Also 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.
