Fig. 4. Stereo view of the active site of
glycosylasparaginase. a, stereo view of superimposition of the
active sites between Flavobacterium (shown according to atom
type: yellow for carbons, blue for nitrogens, and red for
oxygens) and human (shown in gray) GA. Also shown is aspartate
in the human enzyme/product structure (13). Dashed lines
correspond to the hydrogen bonds described in the human
structure. b, the same stereo view of active site in the T152C
mutant. The color scheme is the same as the wild type in (a),
except that sulfur of the thiol group is shown in green.
