(A) Surface views of the interfaces between Cas13a and duplex formed by crRNA and anti-tag RNA.
(B) Recognition of tag:anti-tag duplex by the Linker and Helical-II domains.
(C and D) Interactions between Cas13a and base pairs 2–6 (C) and 7–15 (D) in the guide:target duplex.
(E) Surface views of pre-target-bound LshCas13a-crRNA complex, with interactions between crRNA tag region and LshCas13a shown in the zoomed-in panel.
