Lifetime of the Chl pool in the presence of Luts. (a) A pool of 6 Chl a’s (together with Chl a612 and Chl a603 representing the Chl a subsystem of an Lhca/Lhcb unit) is equilibrating with Chl a612/Chl a603 which in turn transfer excitation to their Car partners Lut 620/Lut 621. (b) The lifetime of the whole complex based on the L1/L2 pigment pair structures from the MD simulation. The inset shows the lifetime distribution based on the MD snapshots. (c) The lifetime of the complex as a function of the Car tilting angles, \({\tau }_{{\rm{complex}}}({\phi }_{yx},{\phi }_{zx})\), calculated for the coarse-grained model a using the L2 site IES, \({J}_{{\rm{L}}2}({\phi }_{yx},{\phi }_{zx})\), for both sites because of the smoothness of this particular IES. The dashed lines indicate the typical time-scales of the light-harvesting regime in the membrane (2 ns37) and the quenched regime under high-light conditions (~400 ps38). The circles represent the actual tilt angles for Lut 621 from the MD trajectory.
