T. Nozawa et al., REACTION CENTERS FROM A NEW HALOPHILIC PURPLE NONSULFUR PHOTOSYNTHETIC BACTERIUM RHODOSPIRILLUM SODOMENSE, Chemistry Letters, (2), 1994, pp. 193-196
Both reaction centers containing and lacking cytochrome c were obtaine
d from a new halophilic photosynthetic bacterium Rhodospirillum (R.) s
odomense. The cytochrome c has a very low reduction potential not to b
e reduced by Na-ascorbate. The special pair bands in the both reaction
centers exists at around 850 nm, some 20 nm to the blue of that of a
nonhalophilic species, R. rubrum.
