Figure 3. Structures and predicted structures of the TSEN proteins.

Depiction of each of the TSEN proteins showing known or predicted structures for each protein, paired with a bar cartoon of the protein. The cartoons show the conserved archaeal building block αN and αC - terminal subdomains and active site residues of the endonucleases are designated by “*”.
A) NMR structure of the TSEN15 (PDB:2GW6). B) Alphafold predicted structure for TSEN34. C) Alphafold predicted structure for TSEN2. D) Alphafold predicted structure for TSEN54.
