Protein Family Models

This presumed domain is about 120 amino acids in length. It is found associated with CBS domains Pfam:PF00571, as well as the CbiA domain Pfam:PF01656. The function of this domain is unknown. It is named the DRTGG domain after some of the most conserved residues. This domain may be very distantly related to a pair of CBS domains. There are no significant sequence similarities, but its length and association with CBS domains supports this idea (Bateman A, pers. obs.). (from Pfam)

This family contains a wide variety of enzymes, principally thioesterases. This family includes 4HBT (EC 3.1.2.23) which catalyses the final step in the biosynthesis of 4-hydroxybenzoate from 4-chlorobenzoate in the soil dwelling microbe Pseudomonas CBS-3. This family includes various cytosolic long-chain acyl-CoA thioester hydrolases. Long-chain acyl-CoA hydrolases hydrolyse palmitoyl-CoA to CoA and palmitate, they also catalyse the hydrolysis of other long chain fatty acyl-CoA thioesters. [1]. 9837940.

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]. Discovery and naming of the CBS domain.. [1]. 9020585.
