Figure 3 Comparison of the structures of Mn: IPNS (a) and
Fe(II): ACV: IPNS (. b) from the same orientation. The
jelly-roll motif is in green, the C-terminal region (residues
313-331) cyan, the active-site metal ion (manganese in a, iron
in b) orange, the key substrate-binding residues (His 214, His
270, Asp 216, Arg 87, Arg 279, Tyr 189 and Ser 281) magenta, and
the ACV yellow.
