Structure perturbation induced by L114P mutation in MfpA. Top view (a) and side view (b) of the superimposed wild type (blue) and L114P mutant (pink) structures after 10-ns MD simulation. Only part of the structure (residue 87 to 148) is shown. The side chain of T117 in the L114P mutant is in green, with red balls for hydroxyl oxygen atom. The side chain of P114 residue is in yellow.
