2,6-DMP oxidation. LPMO catalyzes the oxidation of 2,6-DMP to the corresponding phenoxy radical at the expense of H2O2. The active-site Cu(II) is reduced by 2,6-DMP which generates the 2,6-DMP radical. Two formed 2,6-DMP radicals dimerize rapidly to hydrocoerulignone, which again is quickly converted to coerulignone by LPMO. The stoichiometry of the peroxidase reaction is 1:1
