Figure 5. The MT1 trefoil knot. Residues 1-190 and 199-229 are shown in solvent accessible surface representation (1.4 Å radius). The knot loop (residues 191-198) is in blue and the polypeptide chain threaded through the loop (residues 230-264) is labeled red. Crossover residues (Ser194 and Asn234) as well as Arg191 on the loop, Trp232 and Glu239 on threaded through chain are marked as a reference points. Carboxy terminus is labeled C .
