Structure of the N-terminus of MgtA. Structure of the N-terminus of Magnesium Transporter A (MgtA) of Escherichia coli (MgtA, PDB: 3GWI). Right panel: zoom in on the surface of the MgATP-binding site with the four binding motifs. The xTG (yellow) is unique to the MgtA protein compared to members of the P-type ATPases. MgATP has been enlarged for illustration purposes and does not reflect the physical bindings sites with the protein
