Polypeptide composition of light-harvesting complexes from some brown algae and diatoms

Abstract The polypeptide composition of some Chromophyte light-harvesting complexes was investigated by SDS-PAGE and compared to LHCP of higher plants. According to the species, one or two major polypeptides were found in the range 17–25 kDa, which is noticeably lower than for higher plant LHCP polypeptides. Evidence is provided for three species LH polypeptides possessing different molecular masses that they all possess some immunological analogy with a maize LHCP. In addition, Fucus serratus LH was proved to be able to phosphorylate.
