【 摘 要 】
The thermodynamic and spectroscopic properties of the membrane bound iron-sulphur centers and cytochromes in phototrophically grown cells of the thermophilic facultative photosynthetic green bacterium Chloroftexus aurantiacus have been examined. The present study shows that Chloroflexus contains several cytochromes of b and c type, along with multiple ferredoxin-like centers with resonances centered at g = 1.93, g = 2.017 (HiPIP-like center) and g = 1.90 (Rieske-type protein). The g = 1.90 centre appears to be actively involved in photooxidative reactions. These observations suggest the presence of a previously undetected cytochrome complex in this bacterium.
