HHsearch alignment for GI: 254780889 and conserved domain: cd04605

>cd04605 CBS_pair_MET2_assoc This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the MET2 domain. Met2 is a key enzyme in the biosynthesis of methionine. It encodes a homoserine transacetylase involved in converting homoserine to O-acetyl homoserine. 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.
