SURFACE LOCALIZATION OF ENZYMES IN MYCELIA AND MICROCONIDIA OF FUSARIUM OXYSPORUM

Abstract

Localization of enzymes in Fusarium oxysporum was investigated. It was found that invertase and sulfhydryl oxidizing activity were localized in the isolated cell-wall fraction of mycelia and microconidia of this fungus, prepared either by toluene and pronase treatment or mechanical disruption. The distribution of the enzyme activities was quite different from that of intracellular localizing enzymes. The physiological implication of the localization of these enzymes was discussed.
