title: Reconstitution of carotenoids into the light-harvesting pigment-protein complex from the carotenoidless mutant of Rhodopseudomonas as sphaeroides R26.
abstract: Two carotenoids, neurosporene and spheroidene, have been successfully added to chromatophores from the carotenoidless mutant of Rhodopseudomonas sphaeroides R26. Carotenoids reconstituted in this way into the B-850 light-harvesting pigment-protein complex both sensitive bacteriochlorophyll fluorescence and protect the complex from the photodynamic reaction.
