The primary electron transfer has been investigated by femtosecond time-resolved absorption spectroscopy in two chemically modified reaction centers (RC) of Rhodobacter sphaeroides, in which the monomeric bacteriochlorophylls BA and BB have both been exchanged by 13(2)-hydroxybacteriochlorophyll a or [3-vinyl]-13(2)-hydroxybacteriochlorophyll a. The kinetics of the primary electron transfer are...

Wang comments that the diffraction data for the structure of the A139T mutant of translocator protein TSPO from Rhodobacter sphaeroides should be used to 1.65 instead of 1.8 angstroms and that the density interpreted as porphyrin and monoolein is better fitted as polyethylene glycol. Although different practices of data processing exist, in this case they do not substantially influence the fina...

Ž . Three pulse photon echo peak shift measurements 3PEPS of the detergent isolated B820 subunit of the light harvesting complex of Rhodospirillum rubrum are presented and compared with 3PEPS data for the LH1 complex of Rhodobacter sphaeroides. The comparison suggests that the 90 fs component of LH1 3PEPS is indeed the energy transfer component. The striking similarity between 3PEPS of LH1 and ...

In this work, reaction center protein (RC) isolated from Rhodobacter sphaeroides purple bacteria was coupled with WO3(∙0.33H2O) via physical adsorption, where vectorial electron transfer (from RCs towards the inorganic carrier) demonstrated using flash kinetics and photoluminescence measurements. The efficiency of interaction between correlated to components’ surface charge at working pH struct...
