Spatial structure information of substrate–enzyme docking. A The position relationship between EcMAL channels and the active sites. The target residues of libraries A–E are displayed in purple sticks. The substrate tunnel is shown in yellow and blue. B Poses of caffeic acid docked in the modeled structure of EcMAL. The substrate caffeic acid is shown in azure and the selected residues envelop the substrate in a surface view. The visualization of EcMAL channel, substrate and target amino acid residues was achieved by Pymol and Yasara
