Figure 4
E82I PaDsbA1 binds a molecule of PEG 400 on its noncatalytic surface. (a) A PEG 400 molecule (yellow sticks) binds at the C-terminal end of H1, making hydrogen-bond interactions with the side chain of Lys53 (b). The OMIT map for PEG 400 is shown (Fo − Fc map contoured at 3σ obtained after refinement of the model in which the PEG 400 molecule was omitted).
