Figure 1. The architecture of the substrate-bound spastin hexamer in a split lock-washer conformation.
(a) Top (Left) and side view (Right) of the EM map of the spastin hexamer with individual protomers colored separately. Substrate density is colored in light green. The ~35 Å gap between protomer A and F is apparent in the sideview. (b) Top (Left) and side view (Right) of the atomic model in ribbon representation. Nucleotides are depicted as space-filling models and the polyglutamate peptide substrate is shown in surface representation.
