Abstract


The subcellular distribution of enzymes involved in the reaction sequence from zymosterol to ergosterol was studied. The spheroplasts obtained from cells aerobically grown on ethanol were gently disrupted and the homogenate was fractionated into the subcellular organelles by differential centrifugation. Inspection of the distribution of several marker enzymes revealed that the fractionation was reasonably effected. As a result of experiments, delta 8-delta 7-sterol isomerase, S-adenosylmethionine: delta 24-sterol methyltransferase and the enzyme involved in the reaction sequence from episterol to ergosterol were localized in microsomes. These results suggest the localization of enzymes involved in the late stage of ergosterol synthesis in microsomes.
