Influence of Polar Mutations on the Electronic and Structural Properties of Q_A^–· in Bacterial Reaction Centers

Technical Report Taguchi, Alexander T. ; Wraight, Colin A. ; Dikanov, Sergei A.

Reaction centers from Rb. sphaeroides with residue M265 mutated from isoleucine to threonine, serine, and asparagine (M265IT, M265IS, and M265IN, respectively) in the Q_A^–· state are studied by high-resolution ESEEM and ENDOR spectroscopies to investigate the structural characteristics of these mutants influencing the redox properties of the Q_A site. All three mutants decrease the redox midpoint potential (E_m) of Q_A by ~0.1 V, yet the mechanism for this drop in E_m is unclear. In this work, we examine (i) the hydrogen bonding interactions between Q_A^–· and residues histidine M219 and alanine M260, (ii) the electron spin density distribution of themore »« less
