    • Formation of a delocalized chlorophyll dimer would depend on occupancy of both A5 and B5 sites by chlorophyll a. Although the A5 site exclusively binds chlorophyll a, B5 is a mixed site of chlorophylls a and b in minor complexes (CP29, CP26, and CP24, 21, Therefore, a delocalized chlorophyll a dimer can form within the A5 and B5 sites in CP29. Moreover, this dimer structure could also explain why Z•+ formation is not favored in LHCII (14, in which the A5 and B5 sites specifically bind chlorophylls a and b, respectively (12, Because the large spectral absorbance gap (∼700 cm-1) between chlorophylls a and b prohibits delocalization over a chlorophyll heterodimer, no CT state can be produced in the L2 site of LHCII. One additional factor of specificity is that the capacity of LHCII to undergo exchange of V to Z in site L2 in vivo is very low relative to minor complexes 22
