Spin labels and maltodextrin-binding protein. (A) Cysteine-reactive nitroxide spin labels used in this study. Atom types are colored as follows: nitrogen (blue), oxygen (red), carbon (gray), sulfur (yellow), and bromine (salmon). Lewis structures are provided in Fig. S1. (B) Maltodextrin-binding protein in the unbound state (PDB: 1OMP). Color-labeled spheres indicate spin-labeled residues. Dashed lines indicate site pairs used in DEER experiments. (C) Same as (B) for the maltose-bound state of MBP (PDB: 1ANF). Maltose is shown as spheres with raspberry carbon atoms and red oxygen atoms. To see this figure in color, go online.
