Abstract
Reaction centers (RC) are membrane-bound electron transfer proteins. The RC of R. sphaeroides consists of 4 bacteriochlorophylls (BChl), 2 bacteriopheophytins (BPh), 2 ubiquinones, 1 Fe2+ and 1 carotenoid molecule embedded in a polypeptide transmembrane matrix. Two BChls constituting the special pair near the periplasmic surface are followed by two monomeric BChls, then two BPhs and the two quinones which are near the cytoplasmic surface. The carotenoid molecule is located near one of the BChl monomers. The position of the chromophores is asymmetric with the BChls and the carotenoid closest to one side of the complex and the BPhs in the middle.
