Fig. 5. Distribution of AABP in RBD using the data from Table S2† (10 matrix Tables) and Table S3†. The three dashed lines shows missing position coordinates of AA. The color bar represents following, light blue: sum AABP of AA with single nearest neighbor, yellow: sum AABP of AA with two nearest neighbors, grey: AA with off-diagonal AABP. The AA marked with purple are conserved ones in the ACE2 receptor binding contact residue area according to Anderson et al. (marked with striped pink box). The red and blue arrow represents the AA with higher negative and positive partial charge.
