Popis: Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has evolved into eight fundamental clades with four of these clades (G, GH, GR, and GV) globally prevalent in 2020. To explain plausible epistatic effects of the signature co‐occurring mutations of these circulating clades on viral replication and transmission fitness, we proposed a hypothetical model using in silico approach. Molecular docking and dynamics analyses showed the higher infectiousness of a spike mutant through more favorable binding of G614 with the elastase‐2. RdRp mutation p.P323L significantly increased genome‐wide mutations (p
Highlights Most dominant spike mutation favors elastase‐2 binding.The polymerase mutant (P323L) virus may speed up replication that corresponds to higher mutations.ORF3a viroporin substitution (Q57H) decreases ion permeability.N protein mutation (RG203‐204KR) can increase nucleocapsid stability and help evade immunity.Co‐occurring mutations might modulate viral replication and transmission fitness through epistasis.
