![Study of the binding of ΔFN3.1 fragments of the <i>Bifidobacterium longum</i> GT15 with TNFα and prevalence of domain-containing proteins in groups of bacteria of the human gut microbiota](https://image.oaes.cc/3d7e6456-8c42-483f-bbed-2531d49eae4b/5610.fig.5.jpg)
Figure 5. Three-dimensional models of ΔFN3.1 proteins from different groups of B. longum subsp. longum using the trRosetta server: (A) group 1 (do not contain amino acid substitutions in comparison to the reference strain B. longum GT15); (B) group 2 (contained a single substitution 43 A→V); (C) group 3 (contained four substitutions 43 A→V, 51 A→T, 417 P→Q and 424 A→T); (D) group 4 (contained three substitutions: 111 T→I, 417 P→Q and 424 A→T).
