Chains Pfam Accession Pfam Identifier Pfam Description Type Source
A PF00478 IMPDH IMP dehydrogenase / GMP reductase domain Domain This family is involved in biosynthesis of guanosine nucleotide. Members of this family contain a TIM barrel structure. In the inosine monophosphate dehydrogenases 2 CBS domains Pfam:PF00571 are inserted in the TIM barrel [2]. This family is a member of the common phosphate binding site TIM barrel family. PFAM PF00478
A PF00571 CBS CBS domain Domain CBS domains are small intracellular modules that pair together to form a stable globular domain [2]. This family represents a single CBS domain. Pairs of these domains have been termed a Bateman domain [6]. CBS domains have been shown to bind ligands with an adenosyl group such as AMP, ATP and S-AdoMet [5]. CBS domains are found attached to a wide range of other protein domains suggesting that CBS domains may play a regulatory role making proteins sensitive to adenosyl carrying ligands. The region containing the CBS domains in Cystathionine-beta synthase is involved in regulation by S-AdoMet [4]. CBS domain pairs from AMPK bind AMP or ATP [5]. The CBS domains from IMPDH and the chloride channel CLC2 bind ATP [5]. PFAM PF00571
