Fig. 4. Contributions of the residues/cofactors to the Qy excitation of α (a) and β (b) BChls in the three complexes. The average value and the standard error bar are shown; the results are computed on 20 frames of MD. Amino acids are displayed using the one letter code (H = his, F = phe, Y = tyr, V = val, W = trp, L = leu, M = met, A = ala), the two adjacent BChls in the ring are displayed using “α” and “β” whereas Z refers to the closest carotenoid and γ to the B800 BChl.
