FIGURE 6.
Phosphorylation of silaffins rSil3 and rSil1L and silacidin rSic in subcellular fractions of T. pseudonana containing ER (F4) and Golgi (F5) membranes. For each assay equal amounts of membranes (10 μg of total protein) were used. The concentration of each substrate protein was 0.1 mg/ml. Kinase activities of intact membranes (−) and membranes solubilized with 1.0% (v/v) Igepal (+) are shown. ⫟, indicates S.D. RLU, relative luminescence units.
