Additional file 6 of Discovery, structural characteristics and evolutionary analyses of functional domains in Acinetobacter baumannii phage tail fiber/spike proteins

Supplementary Material 6: Fig. S6. Trimeric surface models of PKDs and β-sheet aggregate. (a) The upper panel presents trimeric surface models of phage tail fiber/spike proteins with identified PKD types (1-4) clearly marked and annotated. In the lower panel, the molecular surfaces of type 2-4 PKDs (type 1 PKD was shown and documented in Fig. 5) are displayed during docking with ethylene glycol, highlighting β-sheets in red and α-helices in yellow. (b) Structural visualization of β-sheet aggregate. The left panel displays both a ribbon view and a surface view of the β-sheet aggregates, marked in orange. The close-up on the right highlights two β-sheets stacked together to form the aggregate.
