(A) X-ray co-crystal structures of TAK1-2 (green, PDB 5J8I) overlaid with TAK1-10 (orange, PDB 5E7R) showing interactions between the oxygen linkage for warhead and Asn161 (blue dashes). (B) X-ray co-crystal structures of TAK1-5 (cyan, PDB 5J7S) and TAK1-7 (gray, PDB 5JH6). Nitrogen linkage results in loss of interactions with Asn161.
