We measured cocrystals of the membrane protein Photosystem I
with its soluble electron acceptor ferredoxin for the first time at the
ALS (Berkeley, CA). Previous data collected at our home source
and at other synchrotron sources showed crystals with very high
mosaicity (2–5%) and a diffraction limit to 7–8 Aresolution. This
first beamtime at ALS was very successful and may represent a
breakthrough for the determination of the crystal structure. 110
crystals, grown under modified crystallization conditions, were
scanned and for the first time, crystals diffraction to 3.5 A were
observed....
