Figure 4. The L1 stalk and Nmd3 adopt multiple states.
-
AOverlap of the four observed states for L1 stalk/Nmd3. T1 (tan) and T2 (purple) are transition states between the fully open (gray) and fully closed (blue).
-
BRigid‐body docking of uL1‐L1‐Nmd3 into T2 state, showing the atomic model overlap between the closed (orange) and T2 position (blue).
-
C, DModel for coordination of Nmd3 action with Sdo1. (C) In the closed conformation of L1 stalk/Nmd3, the eL22‐like domain of Nmd3 occupies the P site where it would clash with domain I of Sdo1. (D) In transition state T2, the clash between Nmd3 and Sdo1 in the P site is greatly reduced, potentially allowing for the accommodation of Sdo1.
