Fig. 5: Arrangement of A0, Acc, and the surrounding protein environment.
From: Structure of the far-red light utilizing photosystem I of Acaryochloris marina
The structural model of PSI from A. marina is superposed with that from T. elongatus (PDB code 1JB0). a Cryo-EM density map of PA, PB, A0A, and A0B. Each map is shown in a mesh representation at 1.0 sigma contour level. b Arrangement of A0, Acc, and the surrounding protein environment. c As in b, but view from the pseudo-C2 axis. d Geometry of PA/PB and Acc (AccA and AccB). Chl d, green; Pheo, orange; water molecule, red. Colors are the same as in Fig. 3.
