Figure 2

Hydrogen-bonding interactions at the Mn(II)-His6 site of Mn(II)- and Ca(II)-bound CP-Ser. Mn(II)-coordinating residues are shown as orange sticks and the Mn(II) ion is represented as a pink sphere. Additional residues are shown as green (S100A8) or blue (S100A9) sticks. The asterisk indicates that the residue is derived from an adjacent “dimer” of the α2β2 tetramer.
