Abstract

Treatment of a sodium dodecyl sulfate-polyacrylamide gel with periodic acid-Schiff (PAS) stain or blotting with Galanthus nivalis agglutinin revealed the presence of several glycosylated polypeptides in a partially purified detergent extract of the membrane fraction of Sulfolobus solfataricus. One of the glycoproteins comigrated with the membrane-associated protein-serine/threonine kinase from S. solfataricus, which had been radiolabeled by autophosphorylation with [(32)P]ATP in vitro. Treatment with a chemical deglycosylating agent, trifluoromethanesulfonic acid, abolished PAS staining and reduced the M(r) of the protein kinase from approximately 67,000 to approximately 62,000. Protein kinase activity also adhered to, and could be eluted from, agarose beads containing bound G. nivalis agglutinin. Glycosylation of the protein kinase implies that at least a portion of this integral membrane protein resides on the external surface of the cell membrane.
