Crystallization of reaction center I of photosynthesis Low‐concentration crystallization of photoactive protein complexes from the cyanobacterium Synechococcus sp

[摘要]

The integral membrane protein complex of the photosystem I reaction center from the cyanobacterium Synechococcus sp. has been isolated and highly purified. At extremely low protein complex concentrations (50 μg/ml), crystallization occurred. The crystals are dichroic, photoactive and show an X-ray powder diffraction pattern.
