Figure 3. Chemical cross-links on the regulatory subunit 2ABG of PP2A might have originated from a stable intermediate folding state.

Figure 3

(A) The comparative model that is most similar to its template structure 2ABA satisfies only 6 of 18 intra-protein cross-links. (B) In contrast, the comparative model that satisfies with 13 cross-links most of the cross-link data has a RMSD of 19.5 Å and is partially unfolded. Green chain of spheres indicate the shortest path between cross-linked lysine pairs that have an SAS distance ≤34.0 Å.
