This is a full surface representation of a CRISPR RNA-guided surveillance complex, Cascade, bound to a ssDNA target based on PDB ID 4QYZ. This model is related to a modified Cascade complex, in which two of the CasC subunits (chains E and G of the PDB) were deleted.
The proteins are in pink (CasA) and green (CasB, CasC, CasD, CasE). DNA in blue and RNA in red.
