1 Esser et al. Crystal Structures of R. sphaeroides bc Supplementary Information Trivariate Gaussian Probability Analysis The superposition of six structures results in sextets of 3D coordinates for every atom position. In the following, the analysis was restricted to Cα atoms representing the loci of the amino acids. If, in general, the positions of a set of atoms were governed only by un-correlated, random errors (as expected for instance of errors within the x-ray diffraction derived coordinates), the distributions around the mean of a sextet three coordinates (x,y,z) would be approximately equal (Esser et al., 2004). In a Gaussian analysis, this would result in a sphere with a volume that when plotted, represents a userselected probability (integrated probability density) of finding an atom inside the sphere. Conversely, non-random or correlated coordinate changes lead eventually to ellipsoids whose longest principal axes indicates the direction of highest positional spread ( motion ). Given three chance variables, x, y, z, and S, which is a region in x, y, z space, the probability of finding S (probability of locating an atom) inside a volume is defined p(s) = ### "(x, y,z)dxdydz = ### "( x r )dx r Volume Volume, where "(x, y,z) is the probability density function (Burnett and Johnson, 996). For trivariate Gaussian distribution, ( x % x ˆ ) T M % ( x r % x ˆ ) "( r x ) = and M is the variance covariance matrix, (2# ) 3/2 $ M e% 2 $ r " v xx v xy v xz % $ ' M = v yx v yy v yz $ # v zx v zy v ' zz &. The v xx, v xy, v xz, v yy, v yz, v zz are variance and co-variance, which are calculated based on, where xˆ = N! x i i= v xy N = # i= ( x! xˆ )( " y! yˆ ) i. For this case, N is the number of contributors (here N=6). i,

2 Esser et al. Crystal Structures of R. sphaeroides bc Principal axes for the probability ellipsoid are determined following a coordinate transformation (new coordinate system x, y, z ) that reduces the cross terms to zero, which is done by an Eigenvector analysis. The transformed M matrix takes the following form " % $ v 0 0 x' x' ' M = $ 0 v 0 ' y' y' $ 0 0 v ' # z'z' &. Consequently, the probability density function after the coordinate transformation becomes where "(x',y',z' ) = U 2 = (x' " x ˆ ')2 + (y' " y ˆ ')2 + (z' " z ˆ ') # x' & (2#) 3/2 e 2 $U 2 $% $% $% x' y' z' # y' # z', The" 2 x'," 2 2 y'," z' are the variances along the principal axes. The normal probability density function is constant for points on the ellipsoid with the value U. To relate U to a probability one needs to solve the equation (here in spherical coordinates): The following tabulates the value of P versus U that can be obtained from mathematical handbooks. P(U) = U 2 " # r2 % r22 $ # e dr 0 P (probability) U

Crystal Structures of R. sphaeroides bc The program Mudi has been written in house that performs the multi (=tri) variate Gaussian analysis (available upon request: It reads superimposed pdb files and writes out arrays of eigenvectors and eigenvalues and appropriate instructions for povray ( Supplementary Figures Figure S Interaction of ISP and cyt c at the periplasmic side of the membrane. Extra lateral support of ISP is provided in Rsbc by the insertion from 60 to 80, which features a disulfide bridge: Cys 69 to Cys 45. In mitochondrial bc, subunit VIII is spatially close and can provide shielding for ISP against the lipid and/or aqueous phase. Cyan (Rsbc ) and magenta (Btbc ) surfaces show spatial overlap in the vicinity of ISP. ISP in light gray is a model of the c -state and the yellow trace outlines the observed position of ISP in Rsbc. The red insertion (97-08) into ISP remains distal to the cyt c heme. Supplementary Tables Table S Distances (Å) between iron atoms in prosthetic groups in dimeric bc complexes.
