Asp314 is essential for the formation of the binuclear metal center. Structural comparison of the WT and catalytically inactive ARH3-D314E mutant reveals a side-chain flipping of Glu314, which leads to the loss of MgB. This suggests that Asp314 is essential for the formation of the binuclear metal center in ARH3 and that MgB is required for catalysis.
