FIGURE 7

Interactions of the extramembrane domain of the cyt f subunit from the cyt b6f complex (PDB code 1Q90) with PC and cyt c6 at 10 mM ionic strength and pH 7.0. The conditions are the same as for Fig. 3. (A) The 1Q90 cyt f and its modified form in which the loop of residues A-184-G-191 is replaced with the corresponding loop from the 1CFM-B cyt f structure (see Methods section) interacting with PC. (B) The 1Q90 cyt f and its modified form interacting with cyt c6. The interactions of 1CFM-B with PC and 1CFM-C with cyt c6 are shown for comparison.
