Abstract: | Summary Haloarculajaponica has a glycoprotein on its cell surface. The cell surface glycoprotein of H. japonica was purified and characterized. It had an apparent molecular mass of 180 kDa in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The carbohydrate content was about 12% (wt/wt). The polypeptide portion contained a large proportion of acidic amino acids, and the sequence of 18 N-terminal amino acids was determined. |
