AliD residues interacting with the two permease subunits (AmiC and AmiD) were identified with LigPlot+ v.2.2 [35]. (A) Upper panel, cartoon depiction of AliD (colored orange) is presented in a manner akin to that in Fig 2B (upper panel). AliD residues involved in the interaction with the permease are labeled and depicted in yellow capped sticks, while the semi-transparent representation illustrates the AliD surface. Peptide 1 is visualized as blue spheres. The boxed inset exhibits a surface representation of AliD (orange), highlighting the positions of residues engaging with AmiC (pink) and AmiD (purple). The orientation of AliD corresponds to that in A, upper panel. The middle panel mirrors the representation in A, upper panel, but with a 60° rotation through the indicated axes. The lower panel replicates the view from A, middle panel, incorporating the two permease subunits, AmiC (pink cartoon), and AmiD (soft purple cartoon). ECD, extra-cellular domain. (B) In the upper panel, a table is provided summarizing AliD residues involved in interactions with AmiD. The lower panel presents a table summarizing AliD residues engaged with AmiC. The symbol ’*’ denotes residues that are absolutely conserved across all five OBPs of the Ami system. The symbol ’#’, on the other hand, designates residues with physicochemical properties conserved throughout all five OBPs of the Ami system., Peer reviewed
