Vc-Cascade-TniQ structure, which adopts a helical (G) architecture where Cas6 forms the head of the complex, six Cas7 subunits form the backbone of the complex, Cas8 forms the tail of the complex in addition to the TniQ dimer. Each monomer of TniQ interacts with the head of the cascade mainly via Cas6 and Cas7.1 to form a head-to-tail TniQ dimer [15]. Adopted from PDB code: 6PIJ https://www.rcsb.org/structure/6PIJ The figure was created with PyMol software [55]
