Charged residues on the surface of DotM. a Electrostatic surface representation of DotM153. Blue and red patches indicate positively and negatively charged surfaces, respectively. Black boxes identify Arg-rich surfaces that were mutated in this study. The boxes are labeled M1-5 according to the nomenclature used to name these mutants (see main text and Table 3), and these labels are colored red for mutants abolishing binding or yellow for mutants that do not affect binding. b Zoom-in into Arg-rich patches contributing to peptide binding. Semi-transparent surfaces are as in A. Residues are in stick representation, color-coded as in Fig. 1c
