Fig. 5

a Comparison of the primary sequences among three membrane-extrinsic electron acceptors. All conserved residues coordinated to the Fe4S4 cluster are indicated with black arrows. This figure was generated using ESPrint 354. b Arrangement of FX, FA, and FB in the CabRC and GsbRC, based on the superposition of their PscB subunits. c Arrangement of FX, FA, and FB in the CabRC and PSI based on the superposition of PscB/CabRC and PsaC/PSI. PDB codes: GsbRC, 6M32; PSI, 1JB0.
