Light-harvesting complex II (B800/850) from the purple bacterium Rhodo
vulum (Rhv.) sulfidophilum has been isolated using a new protocol. It
has been shown by analytical ultracentrifugation and native gels to be
most likely an octamer. Two-dimensional crystals have been obtained b
y microdialysis The plane group is p42(1)2 with a=b=157 Angstrom. The
crystals diffract to 18 Angstrom in negative stain. Projection maps sh
ow clearly that LHII is organized in ring-like particles with an outer
diameter of about 76 Angstrom.
