Abstract
Phenolase activity has been found in chloroplast, mitochondrial, and soluble fractions of homogenates prepared from sugar-beet leaves. The phenolases present in the three fractions have different catecholase/cresolase ratios and respond differently to inhibitors. The chloroplasts contain about half the cresolase activity of a leaf homogenate, whereas the bulk of the catecholase activity is present in the soluble fraction. The findings are discussed in relation to the possible mode of action of catecholase and cresolase.This publication has 6 references indexed in Scilit:
