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.

Description

An archaeal family of CBS domain (see <PDOC51371>) proteins that are able to function as electron transfer proteins contains a small (~35 amino acids) C-terminal metal-binding (MB) domain containing four cysteine residues arranged in a Cys-X(2)-Cys-X(14-19)-Cys-X(1-4)-Cys motif. The archaeal CBS proteins (ACP)-type MB domain can bind several metals, with iron and zinc being the most abundant metals [1].

The ACP-type MB domain consists of three short β-strands forming a compact anti-parallel β-sheet that packs against the CBS domains (see PDB:1PVM>) [1].

The profile we developed covers the entire ACP-type MB domain.
