Figure 4.
Figure 4. C[  ]trace
and stereo view of MT1-DD and MT1-CSD structural overlap. (a)
The MT1-DD (red) is shown overlapped with the corresponding
domain of MTHFR (green). Corresponding  -helices
and  -strands
are labeled as and
,
respectively, according to numbering convention for MTHFR. (b)
The small domain of MT1 (red) is shown overlapped with 1SRO
(green), 1MJC (blue), and 1FJF_Q (orange). Figures were prepared
with the program MOLSCRIPT.^33 Residues were deleted from
proteins where appropriate to simplify the diagram. Refer to
text for PDB identifiers.

Figure 5.
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
 .
Figure was prepared with WebLabPro.
