SARS-CoV-2 spike ectodomain (HexaPro, Omicron BA.2 variant) in complex with CeSPIACE

Severe acute respiratory syndrome coronavirus 2

the N-terminal sequence (from -18 to 12) is an mammalian secretion signal sequence, and the C-terminal sequence includes "T4 fibritin trimerization mottif" (Gly1211-Leu1237), "HRV 3C protease cleavage site" (Leu1241-Pro1248), "8x His tag" (His1250-His1257) and "Twin-strep tag" (Trp1260-Lys1288)
