RESUMO
Triton extracts of intracytoplasmic photosynthetic membranes (chromatophores) purified from Rhodopseudomonas sphaeroides were subjected to crossed immunoelectrophoresis with antiserum raised in rabbits to purified chromatophores. A total of 31 immunoprecipitates was visualized; 2 of the immunoprecipitates were identified as reduced nicotinamide adenine dinucleotide (EC 1.6.99.3) and L-lactate dehydrogenases by enzyme staining techniques. Reaction with a monospecific antiserum identified the photochemical reaction center. Photopigments were associated with a major precipitate in the pattern which was identified on the basis of immunological identity as light-harvesting bacteriochlorophyll a . protein complex. These results provide the basis for a detailed structural and functional analysis of the chromatophore membrane by crossed immunoelectrophoresis.
