Investigation of Quinone Reduction in Rhodopseudomonas viridis by FTIR Difference Spectroscopy and X-Ray Diffraction Analysis... 

Recently we improved the reaction center isolation procedure - A purified preparation still containing the H subunit, and displaying a stable photochemical activity, was obtained - In this article we will compare some functional properties of this reaction center preparation with reference to Rhodopseudomonas viridis and Rhodobacter sphaeroides. Similarities are found with the former at the level of the acceptor quinone complex the structure of the primary donor in both the reduced and oxidized states, as determined by Fourier transform resonance Raman spectroscopy, resembles the latter.
