Abstract
Abstract 2,3-Naphthalenediol is shown to be a competitive inhibitor of phenolases from a number of plant species, including those in chloroplasts, mitochondria and soluble fractions prepared from apples. A soluble laccase-like enzyme present in peaches however is not inhibited by the diol. The inhibitory properties of other naphthalene derivatives were investigated. The inhibition of phenolase by the diol is discussed on the basis of its inability to undergo keto-enol tautomerism and the results related to the possible reaction mechanism of the oxidation of phenols by phenolase.
