• VP35 of Ebola viruses (EBOVs) is an attractive potential target because of its multifunction. All-atom molecular dynamics (MD) simulations and Molecular Mechanics Generalized Born surface area (MM/GBSA) energy calculations are performed to investigate the single-walled carbon nanotube (SWCNT) as an inhibitor in wild-type (WT) VP35 as well as in three primary mutants (K248A, I295A, and K248A/I295A) through docking the SWCNT in the first basic patch (FBP) of VP35. The SWCNTs of all the four systems effectively bind to the FBP. Interestingly, the sites and orientations of the SWCNT binding to the I295A mutant and K248A/I295A double mutants change significantly to accommodate the variation of the VP35 conformation. Moreover, the VDW can provide the major forces for affinity binding in all four systems.
