Figure 1. X-Ray Crystal Structure of NOD•ADP and NOD•AMPPNP
(A) Structure of NOD•ADP is shown. ADP is displayed as a ball-and-stick model.
(B) NOD•AMPPNP is shown as in (A).
(C and D) Superposition of NOD•ADP (blue) and NOD•AMPPNP (orange) through alignment of the P loop (G87-S94) as viewed from the top (C) and from the side (D). Arrows highlight the differences between the two states in Sw1, Sw2, α3, and L11.
(E) Configuration of hydrogen bonds between Sw1/Sw2 residues in NOD•ADP. Hydrogen bonds with measured distances are highlighted with magenta dashed lines. The water molecules that coordinate Mg^2+ are shown as red spheres.
(F) Active site configuration of hydrogen bonds for NOD•AMPPNP in a similar orientation as (E).
