Fig. 7. 3d surface of the calculated total AABP and off-diagonal AABP in RBD: (a), (b), and (c) shows the sum AABP in different orientations around the vertical directions. AAs with higher sum AABP on surface are Gly504, Tyr505, Arg509, Cys336, Asp389, and Lys386. (d), (e), and (f) shows off-diagonal part of AABP in same orientation as in (a), (b) and (c). The AAs with higher off-diagonal AABP surface are Tyr505, Thr500, Arg509, Cys336, Asp389, and Lys386. Asn343 glycan, which is only AA in RBD out of the 22 N-linked glycosylation in the S protein is also marked in all figures.
