Figure 2.
FIG. 2. Ribbon representation of tyvelose epimerase. The
tetrameric structure of the enzyme is shown in a. The A/B and
C/D pairs of dimers are similar to the dimers observed in both
the human and bacterial forms of UDP-galactose 4-epimerase.
Bound ligands are depicted in ball-and-stick representations. A
stereo view of one subunit of the tetramer is shown in b. The
molecular architecture of the subunit can be envisioned as two
lobes, as indicated in blue and green. The active site is wedged
between these two lobes.
