We are deeply saddened by the passing of Amos Bairoch (1957–2025), the creator of PROSITE. We wish to dedicate our latest paper, published shortly before his death, to him. He will always be a source of inspiration to us.
Our deepest condolences go out to his family and friends, and to all those who had the privilege of working with him. Rest in peace, Amos. Your work will live on long after you are gone.
Amos Bairoch

Predictors PROSITE; PS51922; BCOV_S1_NTD
Name Betacoronavirus spike (S) glycoprotein S1 subunit N-terminal (NTD) domain
Function The receptor binding domain (RBD) of betaCoV that directly engages the receptor is commonly located in the C-terminal half of S1 [C-terminal domain (CTD)] such as in SARS-CoV, SARS-CoV-2, MERS-CoV,and BatCoV HKU4, though in rare cases such as with mouse hepatitis virus (MHV), the RBD region was identified in the S1 N-terminal domain (NTD).
