Additional file 4 of Discovery, structural characteristics and evolutionary analyses of functional domains in Acinetobacter baumannii phage tail fiber/spike proteins

Supplementary Material 4: Fig. S4. Structural modeling of β-Helix topology in tail fiber/spike proteins not annotated by InterPro as containing PLD. This figure presents the structural modeling of β-helix topology in tail fiber/spike proteins previously reported to have depolymerase activity but not annotated by InterPro (AbTJ 3714, AbP2 2740, vB_AbaM_IME285 16841). The structures reveal short α-helices and β-strands, both highlighted in red, seamlessly integrated into the β-helix units without disrupting their overall topology or functionality.
