Comparisons of molecular interactions in PelNs in the process of mutation of G241V. The molecular interactions were modeled by the Discovery Studio 4.1 program. The residues in which the molecular interaction has changed are colored pink. The residues are represented in the stick scheme. The hydrogen-bonding interactions are displayed by black dashed lines. a Hydrogen-bonding interactions of the wild PelN, b hydrogen-bonding interactions of the G241V variant, c salt bridge interaction of the wild PelN, d salt bridge interaction of the G241V variant
