Fig. 1: Two structural forms of the CabRC.
From: Structure of the Acidobacteria homodimeric reaction center bound with cytochrome c
a Structure of the CabRCS complex viewed along the membrane plane from the front (left) and the periplasmic side (right). b The structure of the CabRCL complex viewed along the membrane plane from the front (left) and side (right). All subunits are shown as cartoon models of different colors. Carotenoids, lipids and unknown molecules are shown as line models and colored light blue. Only the main tetrapyrrole rings are shown for (B)Chls, and are colored green. Only the main tetrapyrrole rings are shown for heme groups, and are colored hot pink. Fe4S4 clusters are shown as yellow and oraspheres.
