Abstract
The tyrosine-(M)210 of the reaction center of Rhodobacter sphaeroides 2.4.1 has been changed to a tryptophan using site-directed mutagenesis. The reaction center of this mutant has been characterized by low-temperature absorption and fluorescence spectroscopy, time-resolved sub-picosecond spectroscopy, and magnetic resonance spectroscopy. The charge separation process showed bi-exponential kinetics at room temperature, with a main time constant of 36 ps and an additional fast time constant of 5.1 ps. Temperature dependent fluorescence measurements predict that the lifetime of P(*) becomes 4-5 times slower at cryogenic temperatures. From EPR and absorbance-detected magnetic resonance (ADMR, LD-ADMR) we conclude that the dimeric structure of P is not significantly changed upon mutation. In contrast, the interaction of the accessory bacteriochlorophyll BA with its environment appears to be altered, possibly because of a change in its position.

Abstract
Photosynthetic organisms transform the energy of sunlight into chemical potential in a specialized membrane-bound pigment-protein complex called the reaction center. Following light activation, the reaction center produces a charge-separated state consisting of an oxidized electron donor molecule and a reduced electron acceptor molecule. This primary photochemical process, which occurs via a series of rapid electron transfer steps, is complete within a nanosecond of photon absorption. Recent structural data on reaction centers of photosynthetic bacteria, combined with results from a large variety of photochemical measurements have expanded our understanding of how efficient charge separation occurs in the reaction center, and have changed many of the outstanding questions.

Abstract
The recently developed technique of Magneto-Optical Difference Spectroscopy (MODS) [10] has been applied to reaction centers (RC) of the photosynthetic bacterium Rhodopseudomonas sphaeroides R-26. Absorbance changes induced by a magnetic field are measured as a function of wavelength yielding the triplet-minus-singlet (T-S) absorbance difference spectrum. (T-S) spectra thus obtained have been measured from 24-290 K. Going from low to high temperature the (T-S) spectra show the following features: (a) A rapid decrease of positive absorption bands at 809 and 819 nm. (b) A slow appearance of a band shift at 798 nm. (c) A shift of the peak wavelength of the Qy absorbance band of the primary donor P-860 from 992 to 861 nm, and of its Qx band from 603 to 600 nm. The spectra at 24, 66, 116, and 290 K have been analyzed by Gaussian deconvolution. The 800 nm region of the spectrum at 24 K can be decomposed in a combination of two band shifts and an appearing band. The temperature dependence of the spectra in this region is well explained by spectral broadening of the two shifting bands combined with a decrease in intensity of the appearing band when the temperature increases.The two shifting bands in the 800 nm region are identified as the two bands at 803 and 813 nm which together make up the 800 nm band in the absorption spectrum and are assigned to the two accessory RC bacteriochlorophylls (BChls). The band shift of the 813 nm pigment is appreciably larger than that of the 803 nm pigment. The appearing band at 808 nm is attributed to monomeric absorption of (3)P-860, the triplet state being localized on one BChl.We find no evidence for admixture of a charge transfer (CT) state of (3)P-860 with one of the accessory BChls at higher temperature.
