Fig. 1: Structure overview of the LH1–RC core complex from Rpi. globiformis.

From: An LH1–RC photocomplex from an extremophilic phototroph provides insight into origins of two photosynthesis proteins

Fig. 1

a Side view of the core complex parallel to the membrane plane. b Top view from the periplasmic side of the membrane. Dotted ovals indicate the positions that lack the γ-like polypeptide. c Side view of surface representation of the complex. Dotted red ovals indicate the positions that lack the γ-like polypeptide. d Tilted view showing distributions of the γ-like polypeptides (magenta cartoons) and cardiolipins (red sticks) in the LH1 ring. e Side view of the Cyt subunit (cyan) in the LH1–RC showing its N-terminal transmembrane domain. Heme groups are shown by paleyellow sticks. Color scheme: LH1-α, green; LH1-β, slate blue; LH1-γ, magenta; RC-C, cyan; RC-L, wheat; RC-M, blue; BChl a, red sticks; carotenoids, yellow sticks; BPhe a, magenta sticks; lipids or detergents, gray.
