(A) Electrostatic surfaces of three Trp-binding pockets on the PIWI domain of AG02 (top, PDB ID: 6CBD) and AG04
(bottom).
(B) Residues forming the Trp-binding pockets of AG02 in complex with tryptophans (pink) (top) and apo-AG04 (bottom).
(C-l) Gel filtration analyses of AG02 (blue), AG04 (green), TNRC6B fragment (pink), and a mixture of the TNRC6B fragment
and either AG02 or AG04 (black).
