The third predicted subsequence is HWKWPWYIWL 1102–1218 with a peak score of 108 relates to IKWPWYIWL in the original Wuhan seafood market isolate (GenBank MN908947.3) and lies at the boundary between the C-terminal end of S2 and the transmembrane part 1214–1273. Its 3D structure is not, to the present author's knowledge, available, as it lies in residues 1147 onward are generally excluded from experimental structure (e.g. VVX and VYB).
