FIG 4.
Intermolecular interactions of the monomers of the ASFV dUTPase. (A) Interactions along the 3-fold axis. The hydrophobic interactions of L105 and I87 residues and a hydrogen-bond interactions network are displayed. The residues are shown as a stick model, and the hydrogen bonds are shown as dashed yellow lines. The black triangle represents the 3-fold axis. (B) Results from the thermal stability test of the ASFV dUTPase. The Tm is identified by plotting the first derivative of the fluorescence emission as a function of temperature (−dF/dT), and the Tm is represented at the lowest part of the curve.
