Structural changes associated with F6P and S7P Schiff-base formation. Superposition of (a) F6P and (b) S7P noncovalent (beige) and Schiff-base-bound (yellow) complexes. Differences in (c) F6P and (d) S7P noncovalent (top panels) and covalent (bottom panels) conformational states result from a ∼0.5 Å translational shift and the calculated rotations around the bond dihedrals ∠O1—C1—C2—O2 (purple), ∠O2—C2—C3—O3 (red), ∠O3—C3—C4—O4 (marine) and ∠O4—C4—C5—O5 (pink). |
