Figure 4
CAMPASS database. Structure-based alignment of the cytochrome superfamily including distantly related proteins such as c550. Helix 2 of 1ycc, conserved within the homologues (see Fig. 3[link]), occurs as an insertion in this alignment. Despite poor sequence identity, the functionally important residues (CXXCH) are conserved amongst the members in this superfamily.
