Phenylalanine residues in the C. virescens (A), D. caldariorum (B), A. aegerita (C), and M. rotula (D) UPOs. Semitransparent solvent access surfaces, phenylalanine residues, and heme cofactor (as CPK-colored sticks) are shown. Red labels indicate residues less than 10 Å from the heme iron. Data are from homology models (A and B) and crystal structures (C and D [PDB entries 2YP1 and 5FUJ, respectively]).
