Fig. 5

a T. elongatus trimer and monomer superposed for illustration of the absence of the C-terminal α-helix and the PsaL-bound carotenoid BCR4022. The C-terminal phenylalanine in our monomer model of PsaL is indicated by a dashed arrow. b Synechocystis sp. trimer and monomer superposed with the C-terminal glutamate of the monomer model of PsaL indicated by a dashed arrow.
