Summary

A high resolution structure is described of the lumen-side domain of cytochrome f. This structure is the first for a polypeptide subunit of cytochrome or bc1 or b6f complexes, and has at least three unique or unprecedented features for a c-type cytochrome: (i) more than one structural domain; (ii) predominantly β-strand; and (iii) the N-terminal α-amino group is the orthogonal (6th) ligand, which is unprecedented for a heme protein.
