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