(A) The domain architecture of RsAgo color-coded by domains.
(B) The sequence and pairing alignments of 5′-phosphorylated 18-mer gRNA (in red) and 24-mer tDNA (in blue); the nucleotides not observed in the structure are shown in gray.
(C and D) 2.1 Å structure of the ternary complex of RsAgo with gRNA and tDNA. The nucleic acid is in a stick representation, while the protein is in a ribbon (C) and a surface (D) representation.
