The phycobilisome (PBS) is an extra-membrane supramolecular complex composed of many chromophore (bilin)-binding proteins (phycobiliproteins) and linker proteins, which generally are colorless. PBS collects light energy of a wide range of wavelengths, funnels it to the central core, and then transfers it to photosystems. Although phycobiliproteins are evolutionarily related to ...

Calmodulin (CaM) binds to the FERM domain of 80 kDa erythrocyte protein 4.1R (R30) independently of Ca(2+) but, paradoxically, regulates R30 binding to transmembrane proteins in a Ca(2+)-dependent manner. We have previously mapped a Ca(2+)-independent CaM-binding site, pep11 (A(264)KKLWKVCVEHHTFFR), in 4.1R FERM domain and demonstrated that CaM, when saturated by Ca(2+) ...
