Moessbauer Studies of Photosynthetic Reaction Centers From Rhodopseudomonas Sphaeroides R-26
Abstract
dc:descriptionZero field Mossbauer measurements on ('57)Fe-enriched reaction centers (RCs) differing in ubiquinone content, detergent, oxidation state, or the presence of o-phenanthroline all show a single quadrupole doublet of similar splitting (DELTA)E(,Q), center shift (delta), and temperature dependence. The results are indicative of high-spin ferrous iron (Fe('+2), S = 2) with an approximately invariant first coordination sphere consisting most likely of 6 (or 5) oxygens and nitrogens. The spectra show no evidence for either of the quinones or o-phenanthroline binding directly to the iron.
