Figure 6.
Figure 6. The orientation of the catalytic triad residues
with respect to the overall fold. (a) Schematic diagram of the
structure of dienelactone hydrolase (PDB accession number 1din)
[43], an a/b hydrolase, viewed from the N-terminal side of the
central b sheet. The three catalytic residues align roughly
parallel to the central b sheet. (b) RGAE viewed from a similar
orientation. The catalytic residues align almost perpendicular
to the central b sheet. The figure was prepared using the
program MOLSCRIPT [42].
