Figure 1.

Ribbon diagram of the chimeric MDH-GOX2 structure (PDB code 1p4c). The portions of the structure derived from wild-type MDH (residues 4–176 and 197–356) are colored wheat, except for the eight β-strands of the β₈α₈ TIM-barrel motif, which are shown as cyan arrows. The portion of the structure derived from GOX (residues 177–196) is shown in magenta. The FMN and sulfate ion in the active site are shown in ball-and-stick representation, with carbon yellow, oxygen red, nitrogen blue and sulfur green. This diagram was prepared using PyMOL (DeLano, 2002 ▶).
