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.

PROSITE; PS51864; ASTACIN |
Name | Astacin-like domain |
| Function | Astacin or M12A family zinc metalloproteases are found in bacteria and animals. They belong to the metzincin protease family and are synthesized as inactive precursors. The zinc atom in these enzymes acts as an electrophilic center to enhance the reactivity of a water molecule prior to nucleophilic attack on the carbonyl carbon of the scissile peptide bond. |
