CBS domains are small intracellular modules that pair together to form a stable globular domain [2]. This family represents a single CBS domain. Pairs of these domains have been termed a Bateman domain [6]. CBS domains have been shown to bind ligands with an adenosyl group such as AMP, ATP and S-AdoMet [5]. CBS domains are found attached to a wide range of other protein domains suggesting that CBS domains may play a regulatory role making proteins sensitive to adenosyl carrying ligands. The region containing the CBS domains in Cystathionine-beta synthase is involved in regulation by S-AdoMet [4]. CBS domain pairs from AMPK bind AMP or ATP [5]. The CBS domains from IMPDH and the chloride channel CLC2 bind ATP [5].

This domain is found at the N-terminus of eubacterial magnesium transporters of the MgtE family Pfam:PF01769. This domain is an intracellular domain that has an alpha-helical structure. The crystal structure of the MgtE transporter [1] shows two of 5 magnesium ions are in the interface between the N domain and the CBS domains. In the absence of magnesium there is a large shift between the N and CBS domains.
