FIGURE 7. Active site structure formed by Asp-56 and
Glu-297 of maize GS1a. a, stereo view of the side chain
structures of Asp-56' and Glu-297 together with ADP, MetSox-P,
and three Mn^2+ ions. b, alignments of short stretches of amino
acid sequences containing Asp-56 and Glu-297 in GSs from M.
tuberculosis (MtGS), S. typhimurium (StGS), maize (GS1 isozymes
GS1a, GS1d, andGS2), Arabidopsis, human, and chicken.
