L1 and L2 pairs’ statistics from Molecular Dynamics simulation. (a) Distribution of the position of the central C16 = C37 bond of the two Luts within one monomer showing the distinction between L1 (red) and L2 (blue) sites. All coordinates and directions in this work are represented in the Chl a reference frame given in Fig. 1e,f. (b,c) Definition of the characteristic angles \({\phi }_{yx}\) and \({\phi }_{zx}\) that the Lut backbone (C9–C30 axis) projections form with the x coordinate axis: \({\phi }_{yx}\) angle corresponds to the projection of the backbone axis in the xy plane (b), likewise, \({\phi }_{zx}\) angle corresponds to the projection of the backbone axis in the xz plane (c). (d,e) The distribution of the \({\phi }_{yx}\,\,\)and \({\phi }_{zx}\) angles for L1 (d) and L2 sites (e) within the full trimer. Distributions of \({\phi }_{yx}\) and \({\phi }_{zx}\) are shown in red and blue, accordingly. The arrows indicate the corresponding average values directly from the crystal structure PDB: 1RWT7 (averaged over all three trimers captured in the structure). The envelopes show the normal distribution fit.
