>cd04593 CBS_pair_EriC_assoc_bac_arch This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains in the EriC CIC-type chloride channels in bacteria and archaea. These ion channels are proteins with a seemingly simple task of allowing the passive flow of chloride ions across biological membranes. CIC-type chloride channels come from all kingdoms of life, have several gene families, and can be gated by voltage. The members of the CIC-type chloride channel are double-barreled: two proteins forming homodimers at a broad interface formed by four helices from each protein. The two pores are not found at this interface, but are completely contained within each subunit, as deduced from the mutational analyses, unlike many other channels, in which four or five identical or structurally related subunits jointly form one pore. CBS is a small domain originally identified in cystathionine beta-synthase and subsequently found in a wide range of different proteins. CBS d
