DE   Lytic cellulose monooxygenase (C4-dehydrogenating).
CA   ((1->4)-beta-D-glucosyl)(n+m) + reduced acceptor + O(2) = 4-dehydro-beta-
CA   D-glucosyl-((1->4)-beta-D-glucosyl)(n-1) + ((1->4)-beta-D-glucosyl)(m) +
CA   acceptor + H(2)O.
CF   Cu(+).
CC   -!- This enzyme, found in fungi and bacteria, cleaves cellulose in an
CC       oxidative manner.
CC   -!- The cellulose fragments that are formed contain a 4-dehydro-D-glucose
CC       residue at the non-reducing end.
CC   -!- Some enzymes also oxidize cellulose at the C-1 position of the
CC       reducing end forming a D-glucono-1,5-lactone residue (cf.
CC       EC 1.14.99.54).
