RPSBLAST alignment for GI: 255764505 and conserved domain: cd04590

>gnl|CDD|73090 cd04590, CBS_pair_CorC_HlyC_assoc, This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the CorC_HlyC domain. CorC_HlyC is a transporter associated domain. This small domain is found in Na+/H+ antiporters, in proteins involved in magnesium and cobalt efflux, and in association with some proteins of unknown function. The function of the CorC_HlyC domain is uncertain but it might be involved in modulating transport of ion substrates. 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. The second CBS domain in this CD is degenerate.. Length = 111
