The 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 M r of the polypeptide is 6588. The protein consists of 58 amino acids, having a polarity of 28%.
