✦ Synopsis

The antenna complexes from Rps. cryptolactis have been isolated and purified. Rps. cryptolactis contains two types of variable antenna complex, B800-850 and B800-820 as well as the 'core' B875 antenna complex. The variable antenna complexes contain more than two types of antenna apoprotein, and have a Bchla:carotenoid ratio of ,-~2:1. They can both be crystaUised, but the B800-820 complex is the easiest with which to get relatively large single 3-D crystals (up to 0.5 mm in each dimension).
