HHsearch alignment for GI: 254780889 and conserved domain: cd04585

>cd04585 CBS_pair_ACT_assoc2 This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains in the acetoin utilization proteins in bacteria. Acetoin is a product of fermentative metabolism in many prokaryotic and eukaryotic microorganisms. They produce acetoin as an external carbon storage compound and then later reuse it as a carbon and energy source during their stationary phase and sporulation. In addition these CBS domains are associated with a downstream ACT domain, which is linked to a wide range of metabolic enzymes that are regulated by amino acid concentration. Pairs of ACT domains bind specifically to a particular amino acid leading to regulation of the linked enzyme. 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 i
