SDS-PAGE of phycobilisomes isolated from sucrose gradients. (A) Coomassie staining of separated phycobilisome components from Δslr1649 (Δ), wild type and complemented (Comp) strains. Both linker proteins (CpcC2 and CpcD), which are absent in Δslr1649 cells, are present in the complemented strain, indicating a wild type phycobilisome structure. The linker proteins CpcC2 and CpcD are absent in the mutant strain (Δ). (B) Zn2+ staining of phycobilisomes separated in SDS-PAGE. The signal intensity of phycobiliproteins isolated from wild type and complemented (Comp) strains seems to be equal in contrast to the reduced signal of the Δslr1649 mutant.
