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 CFEM) domain
Function Common in Fungal Extracellular Membrane (CFEM) proteins, characterized by a distinctive pattern of eight cysteine residues of conserved interspacing, are widespread among fungi. The CFEM domain adopts a helical-basket fold that consists of six alpha-helices, and is uniquely stabilized by four disulfide bonds formed by its eight signature cysteines.
