Abstract
The main structural glycoprotein of the cell wall of Chlamydomonas reinhardii has been cleaved by thermolysin into glycopeptides which have been separated into three fractions, T1, T2 and T3. These correspond to three distinct domains within the glycoprotein, characterized by the asymmetric distribution of both sugars and amino acids, in particular hydroxyproline. T2 is very rich in hydroxyproline (43 mol %) and is highly glycosylated, while T3 is poor in hydroxyproline and contains very little carbohydrate. The results are discussed in terms of cell wall glycoproteins and their function.
