Abstract

-type PSII-LHCII supercomplex, the N-LHCII is positioned closer to the PSII core than in C. reinhardtii, likely owing to loss of the linker motif in the N-terminal region of B. corticulans CP29. Structure-based energy transfer analysis suggests that this spatial rearrangement enhances the efficiency of excitation energy transfer from N-LHCII to the PSII core. Collectively, these findings reveal structural adaptations that underlie the acclimation strategies of siphonous green algae inhabiting intertidal environments.
