Fig. 5

Representative gel image of the protein composition of the five AEC fractions determined by SDS-PAGE. Numbers 1 to 5 in Fig. 5 correspond to the respective fractions depicted in Fig. 1. Lanes 2 to 5 are derived from the original gel depicted in Additional file 7A, lane 1 is derived from the original gel shown in Additional file 7B. Proteins were stained with colloidal Coomassie Brilliant Blue. M denotes the molecular weight markers. For detailed information on the nature of the protein bands see section ‘Protein composition of the separated pigment protein complexes’. MS data for the 18 and 21 kDa FCP bands of lanes 2 to 5 (i.e. AEC fractions 2 to 5) are provided in Additional file 5. MS data for the complete analysis of photosynthetic proteins of fractions 1 to 4) can be found in Additional file 6
