Chirino AJ, Lous EJ, Huber M, Allen JP, Schenck CC, Paddock ML, Feher G, Rees DCCrystallographic analyses of site-directed mutants of the photosynthetic reaction center from Rhodobacter sphaeroidesBiochemistry v33, p.4584-4593Seven site-directed mutants of the bacterial photosynthetic reaction center (RC) from the 2.4.1 and WS 231 wild-type strains of Rhodobacter sphaeroides have been crystallized and their X-ray diffraction analyzed to resolutions between 3.0 and 4.0 A. The mutations can be divided into four distinct categories: (1) mutations altering cofactor composition that affect electron transfer and quantum yield, His M202-->Leu (M202HL), His L173-->Leu (L173HL), and Leu M214-->His (M214LH); (2) a mutation in the proposed pathway of electron transfer altering electron-transfer kinetics, Tyr M210-->Phe (M210YF); (3) a mutation around the non-heme iron resulting in an iron-less reaction center, His M219-->Cys (M219HC); and (4) mutations around the secondary electron acceptor, a ubiquinone, affecting proton transfer and quinone turnover, Glu L212-->Gln (L212EQ) and Asp L213-->Asn (L213DN)....
