Figure 2.
Figure 2: Nucleotide-dependent movements of the mechanical elements of kinesin motors. a, Reorientation of the neck linker between the ADP (yellow) and ATP-like (red) states of KIF1A. b, Superposition of the switch II clusters of the plus-end-directed kinesins. Conformation of the switch II cluster (ADP or ATP-like, yellow and red, respectively) controls position of the kinesin neck linker in all structures. Helix 6 is shown in blue. c, Hypothetical model for the nucleotide-dependent dynamics at the core/neck interface of the minus-end-directed motor ncd^9. The colours are the same as in a and b. The switch II cluster and the neck in ATP state are dashed. Conserved residues essential for stabilization of the neck/core interface in the ADP state of the ncd^9 are labelled.
