SARS-related coronavirus is a member of the genus Betacoronavirus (group 2) and monotypic of the subgenus Sarbecovirus (subgroup B). [13] Sarbecoviruses, unlike embecoviruses or alphacoronaviruses, have only one papain-like proteinase (PLpro) instead of two in the open reading frame ORF1ab. [14]
Spike (S) glycoprotein (sometimes also called spike protein, [2] formerly known as E2 [3]) is the largest of the four major structural proteins found in coronaviruses. [4] The spike protein assembles into trimers that form large structures, called spikes or peplomers, [3] that project from the surface of the virion.
