Oxidising Enzymes

O. a basis of the original conception of Bach and Chodat, the authors have considered the mechanism of the oxidase of the higher plants to be as follows: firt, the formation of an organic peroxide from the dihydroxy-group charac- teristic of catechol, this reaction being catalysed by an oxygenase; second, the decomposition of this peroxide (or of hydrogen peroxide derived from it by the action of water) with the production of active oxygen, this reaction being catalysed by a peroxidase. The active oxygen so formed will oxidise guaiacum and other acceptors. The actual form of peroxide derived from
