Figure 2.
Graphical presentation of the active site cavity of DAAO in complex with both enantiomers of Ala at different pH. The active site residues, the L-Ala and D-Ala molecule were shown in stick representation colored in green (carbon atoms), blue (nitrogen atoms) and red (oxygen atoms). The molecular modeling displayed DAAO in complex with D-Ala at pH 7.0 (a), DAAO in complex with L-Ala at pH 7.0 (b), DAAO in complex with D-Ala at pH 9.8 (c), DAAO in complex with L-Ala at pH 9.8 (d), respectively.
