Fig. (2A) The putative furin cleavage site (highlighted by red color) located in the region that was similar to the S1/S2 cleavage site of SARS-CoV (indicated by the arrow). The protein sequences of SARS-CoV-2 (NC_045512.2) and SARS-Cov (NC_004718.3) were picked up for complete alignment with software Clustal X2 [25].
