title: Differential location of regulatory and nonregulatory trehalases in Candida utilis cells.
abstract: The isolation of vacuoles by density gradient centrifugation of protoplast lysates from Candida utilis cells showed a high specific activity for nonregulatory trehalase in vacuoles whereas the regulatory trehalase activatable by phosphorylation behaves as a cytoplasmic enzyme. The vacuolar trehalase is a glycoprotein that can be precipitated by Con A-Sepharose. Treatment of this enzyme with endo H reduced its reactivity with the lectin without loss of enzyme activity and decreased its apparent molecular weight by gel filtration.
