Archaeal CBS proteins (ACP)-type metal binding (MB) domain profile





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.
