EPR detected triplet formation in a single crystal of reaction center protein from the photosynthetic bacterium Rhodopseudomonas sphaeroides R-26

AbstractSingle crystals were obtained from the photosynthetic bacterium Rhodopseudomonas sphaeroides R-26. At low temperatures these crystals are highly photoactive, as is demonstrated by the observation of the T0-populated donor triplet state. The angle dependence of the transitions of this triplet state showed that the space group of this crystal is orthorhombic.Bacterial photosynthesis Rhodopseudomonas sphaeroides R-26EPRReaction center tripletProtein crysta
