Abstract

The glycoprotein nature of legumin and vicilin, the reserve globulins in the cotyledons of Pisum sativum was studied. Legumin from mature seed was found to contain 1% neutral sugars (mannose and glucose) and 0.1% amino sugar (glucosamine), whereas vicilin contained 0.3% neutral sugar (mannose) and 0.2% amino sugar (glucosamine). On the basis of the incorporation of 14C-labeled glucosamine, it appeared that not all of the component subunits of the reserve proteins are glycosylated to the same extent. In addition, it has been established that glycosylation occurs after peptide synthesis. During seed development there was a change in neutral sugars and amino sugar ratio in vicilin. During germination, the neutral sugars and the amino sugar content of the glycoproteins declined. These findings are discussed in relation to the synthesis and degradation of the glycosyl component of the glycoproteins.
