Abstract

The primary charge separation process in reaction centers isolated from the green photosynthetic bacterium Chloroflexus aurantiacus has been investigated with picosecond transient absorption techniques. Transient spectra and kinetics are compared with those obtained under identical conditions on reaction centers from the purple bacterium Rhodopseudomonas sphaeroides. An early electron acceptor complex in both organisms appears to involve interacting bacteriopheophytin-a and bacteriochlorophyll-a molecules. However, there are significant spectral and kinetic differences in the two reaction center preparations.
