The change of physicochemical properties due to mutations from sequence of 6ACC for SARS-CoV to 6VSB for SARS-CoV-2. The two rows on top are sequences of 6ACC and 6VSB, and the residues in red are highly conserved, blue are less conserved and gray are unaligned. The physicochemical properties are listed in the left column. The “ + ” sign indicates an increase in the property after mutation; the “−” sign indicates a decrease in the property after mutation.
