The complete amino acid sequence of the large bacteriochlorophyll-binding polypeptide B870α from the light-harvesting complex B870 of Rhodopseudomonas capsulata

AbstractThe larger (α) of the two bacteriochlorophyll-binding polypeptides of the antenna complex B870 of the photosynthetic apparatus of Rhodopseudomonas; capsulata was extracted by chloroform-methanol-ammonium acetate from the intracytoplasmic membrane and purified by column chromatography on LH60. The complete amino acid sequence has been determined. The Mr of the polypeptide is 6588. The protein consists of 58 amino acids, having a polarity of 28%
