Binding model of Si5g32240 to nitrate by molecular docking. (A) The 3D Si5g32240-nitrate interaction model. The conserved Pro511 was marked in pink. (B) The 2D Si5g32240-nitrate interaction model. Dashed lines indicated potential covalent bonds between Lys182 and NO₃ ⁻, and the eyelash indicated the non-covalent bonds between Tyr95, Ser99, Ser178 and NO₃ ⁻. The 3D and 2D interaction models of the other 91 NPFs could be obtained from Supplementary Data 2 and Supplementary Data 3, respectively.
