Abstract: | Glycophorin A was phosphorylated using protein kinases and the new protein was investigated using31P NMR spectroscopy. Most of these ~30 moles of phosphate were found to be attached to Ser and Thr. Some of these phosphate residues appear to be affected by the carbohydrate residues present. The phosphorylated protein appears to be in a severe state of aggregation, with the degree of aggregationpH-dependent. |
