Conclusions Structures in which Met is surrounded by three aromatic groups are identified in all styles of proteins. In contrast to our former surveys that targeted solely on sulfur romatic groups [9,10], this perform presents a more extensive point of view, the place dipolar interactions on the entire Met thioether interacts with nearby aromatic groups. Inspection of selected examples display that Met romatic 3-bridge clusters could play roles in catalysis and in redox reactions. Examination applying computational methods propose that clusters is usually viewed, in some means, as weaker analogs of cationinteractions. The 3-bridges are characterized by a combination of interactions in between the Met-sulfur, Met-CH2 , and MetCH3 groups, as well as the systems of close by aromatics. This weaker dipole ipole interaction may perhaps strike an energetic stability amongst purely hydrophobic interactions and stronger cationmoieties, allowing a degree of protein flexibility whilst preserving the protein’s native construction. Importantly, the entire Met-thioether is involved in 3-bridge clusters. The int
