RPSBLAST alignment for GI: 255764505 and conserved domain: cd04603

>gnl|CDD|73103 cd04603, CBS_pair_KefB_assoc, This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the KefB (Kef-type K+ transport systems) domain which is involved in inorganic ion transport and metabolism. CBS is a small domain originally identified in cystathionine beta-synthase and subsequently found in a wide range of different proteins. CBS domains usually come in tandem repeats, which associate to form a so-called Bateman domain or a CBS pair which is reflected in this model. The interface between the two CBS domains forms a cleft that is a potential ligand binding site. The CBS pair coexists with a variety of other functional domains. It has been proposed that the CBS domain may play a regulatory role, although its exact function is unknown.. Length = 111
