Homology models of the most recent common ancestors of the MnP-DDQ and MnP-ED subfamilies. Left, scheme of the overall structures of the ancestral MnP-DDQ (A) and MnP-ED (B) dated 128 Ma and 150 Ma, respectively (see Fig. 5), showing α-helices (cylinders), the heme cofactor (CPK sticks) with the iron center (red sphere), two structural calcium ions (grey spheres), disulphide bonds (red sticks), and one Mn2+ ion (pink sphere); Right, views of the Mn2+ coordination spheres with Asp35/Asp177/Gln333 and Glu36/Asp176 contributing to the Mn2+-binding site in the ancestral MnP-DDQ and MnP-ED, respectively (residues previously thought to be participating on Mn2+ binding are indicated in black font)
