Figure 3.
Structure–function relationship between Urm1 and MoaD (PDB
code 1FMA chainD). (A and B) Solvent-exposed residues (yellow
balls) and nearby electrostatic residues (sticks, Arg in blue
and Asp in red) were superimposed on the ribbon representation
of Urm1 (A) and MoaD (B). (C and D) Electrostatic surface
diagrams of Urm1 (C) and MoaD (D). The surface color reflects
the magnitude of the electrostatic potential: red, negative;
blue, positive; white, neutral. All of the surfaces were
observed from the same orientation.
