Figure 3. : Protein modeling studies showing the superimposition image of L559V mutant (yellow) and wild type conformers (cyan). Only the mutant structures in which deviations were observed are shown. The conformational changes in the secondary structure elements are marked for the amino acid residues 544–549 (A), 552–560 (B) and 563–572 (C), respectively. The changes were mainly observed in non-covalent hydrophobic interactions.
