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

Name Streptococcal M proteins D repeat
Function M proteins belong to a family of fibrous streptococcal surface proteins which represent major virulence factors due to their antiphagocytic activities. All M proteins share a common framework that includes a conserved signal peptide, a hypervariable amino terminus, a less variable central domain, and a highly conserved C-terminus. A number of repeat sequences (A, B, C and D repeats) follow the hypervariable region. Sequence conservation increases from the A repeats to D repeats.
