FIG. 4.
Stereoview of alignment of the Cα backbones of the MsrAMtb, MsrABt, and MsrAEcoli crystal structures shown in blue, green, and orange, respectively. N and C termini are designated according to the same color code. MsrAMtb Cα atoms align to those of MsrABt with an RMSD of 1.5 Å for 161 target pairs and to MsrAEcoli with an RMSD of 1.6 Å for 161 target pairs. The C terminus of MsrAMtb exhibits the largest structural variation when compared to MsrABt and MsrAEcoli (see text).
