| Sumario: | (A) Crystal structure of the AliD:peptide 1 complex. Left, ribbon representation of the AliD:peptide 1 complex (ligand shown in yellow caped sticks). Domains I, II, and III are labeled and colored green, light orange and blue; respectively. Right, a magnified view (corresponding to the boxed area shown in the left panel) highlighting amino acid residues engaged in the recognition of peptide 1 by AliD. Polar interactions are indicated by dotted black lines. The sequence of peptide 1 (FPPQNV) is illustrated in yellow capital letters. (B) The crystal structure of AliB in complex with peptides 2, 3 and 4. AliB, as observed in the AliB:peptide 2 complex, is depicted as a white cartoon. The substrates are represented with their secondary structure elements and are color-coded as yellow (peptide 2), green (peptide 3) and blue (peptide 4). (C) Stereo view illustrating polar interactions between AliB (white sticks) and peptide 2 (yellow sticks). (D) Stereo view showcasing polar interactions between AliB (white sticks) and peptide 3 (green sticks). (E) Stereo view illustrating polar interactions between AliB (white sticks) and peptide 4 (blue sticks). (F) Ribbon representation of AmiA in complex with peptide 4 (depicted as yellow capped sticks). (G) Stereo view providing specific details of peptide 4 recognition by AmiA. The relevant residues and crystallographic water molecules are depicted as gray-capped sticks and red spheres, respectively. Residues participating in hydrophobic interactions have been omitted for clarity. P1 to P6, pocket 1 to pocket 6. Pockets beyond substrate position 6 have been omitted for clarity. |
