Fig. 3: Structural evidence for the UV induced removal of diulfide adducts.

Fo-Fo difference maps contoured at 3 σ of the aged dataset from light dataset, centered on (A) chain A C41, (B) chain A C108 and C110, (C) chain X C41 and (D) chain X C108 and C110. Atom-to-atom distance difference plots showing effect of global motions exhibited by the first principal component aligned with light structure relative to aged structure for (E) chain A and (F) chain X.
