Fig. 4: Cryo-EM density maps around P740, Acc and A0.
From: Structure of the far-red light utilizing photosystem I of Acaryochloris marina
Each map around P740 (a, b), Acc (c, d), and A0 (e, f) is shown in a mesh representation at 3.0 sigma contour level for a, b, e, and f, and 5.0 sigma for c and d for ease of recognition of the water molecule coordinating the Mg2+ of chlorin. Colors are the same as in Fig. 3.
