Binding model of GDH1 to NH4+ by molecular docking. The 3D AtGDH1-NH4+ interaction model (A). The 3D PnGDH1-NH4+ interaction model (B). The 3D StGDH1-NH4+ interaction model (C). The 3D ZmGDH1-NH4+ interaction model (D). The 2D AtGDH1-NH4+ interaction model (E). The 2D PnGDH1-NH4+ interaction model (F). The 2D StGDH1-NH4+ interaction model (G). The 2D ZmGDH1-NH4+ interaction model (H). Dashed lines indicate a potential interaction between amino acid residues with NH4+. The black balls showed carbon atoms, the blue balls showed nitrogen atoms whereas the red balls showed the oxygen atoms. The residues involved in non-bonding interactions were shown as red bristles
