EC Tree
IUBMB Comments
This copper-containing enzyme, found in fungi and bacteria, cleaves cellulose in an oxidative manner. The cellulose fragments that are formed contain a D-glucono-1,5-lactone residue at the reducing end, which hydrolyses quickly and spontaneously to the aldonic acid. The electrons are provided in vivo by the cytochrome b domain of EC 1.1.99.18, cellobiose dehydrogenase (acceptor) . Ascorbate can serve as the electron donor in vitro.
