Figure 1.
Ribbon representation of the three-dimensional structural model of the monomeric form of Ec ProRS. The homology model was derived from the X-ray crystal structure of Ef ProRS (PDB code: 2J3L).16 The catalytically important residues and the GXXXP motif of Ec ProRS are shown by licorice representation; the Ef ProRS residues are shown in parentheses.
