The [P12W]-TC16b structure determined by NMR40 showing the backbone and the three aryl residues. The Cβ locations at P18 and L7 are shown to indicate the position that would be taken up by added indole rings in P18W and L7W mutants. The right panel clearly shows the hydrophobic core, with W6Hε3 labeled in green. The distance between Y3 and W6 is ~7 Å.
