Nascent Quinones, Amine Addition In order to generate a model for the reaction of proteins with nascent quinones, catechol and 4-methylcatechol were oxidized with silver-I-oxide in glacial acetic acid or with mushroom tyrosinase (EC in phosphate buffer, respectively. The structures identified indicate that not only the amine reacts with the quinone by the well known addition-oxidation-mechanism, but also that solvent molecules may participate in product formation. The m ain product of
