title: Sterol glucosylation by the plasma membrane from cotyledons of Phaseolus aureus.
abstract: Membrane fractions were isolated from dark grown cotyledons of Phaseolus auneus by differential and sucrose density gradient centrifugation. Endoplasmic reticulum-, Golgi apparatus- and plasma membrane-rich fractions were identified by their respective enzymic activities and tested for their ability to transfer glucose from UDP-glucose to endogenous sterols to form steryl glucosides. The glucosyltransferase activity was shown to be located mainly at the plasma membrane.
