FIG. 3.
Characterization of the polypeptides present in the glycogen-protein complex fraction F2. (a) Fraction F2 was analyzed by 2-D NEPHGE. Protein spots were visualized by staining with Coomassie blue. (b) Cells of S. acidocaldarius were labeled in vivo with H332PO4. Fraction F2 was obtained and analyzed by 2-D NEPHGE. Upper panel, portion of the 2-D gel containing P60.1, P60.2, and P60.3 stained with Coomassie blue; lower panel, autoradiography of the same gel showing 32P-labeled P60.2 and P60.3.
