Inhibition and substrate specificity of lettuce phenolase



Inhibition and substrate specificity of lettuce phenolase



Phytochemistry 1(4): 237-239



The effect of phenylthiourea and carbon monoxide on a soluble and a mitochondrial phenolase from lettuce is described. Differences in inhibition, depending on the substrates oxidized, were observed and the implications of this, as far as deductions about metabolic pathways are concerned, are discussed. The rate of oxidation of a number of p-substituted dihydroxy phenols was determined. It appears that oxidation is by electrophilic attack. The possible reaction mechanism and the probable importance of enol-keto tautomerism of the phenol are discussed.
