Crystal structure of a hypothetical protein, TTHA0829 from Thermus thermophilus HB8, composed of cystathionine-beta-synthase (CBS) and aspartate-kinase chorismate-mutase tyrA (ACT) domains
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 ...
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].
This entry represents the ACT domain found at the C-terminal of TTHA0829, a hypothetical protein from Thermus thermophilus HB8 [1]. This protein may act as a cell-stress sensor or a metabolite acceptor [1]. This protein contains a CBS (Pfam:PF00571) ...
This entry represents the ACT domain found at the C-terminal of TTHA0829, a hypothetical protein from Thermus thermophilus HB8 [1]. This protein may act as a cell-stress sensor or a metabolite acceptor [1]. This protein contains a CBS (Pfam:PF00571) at the N-terminal. TTHA0829 can form dimers or tetramers through several inter-domain interactions.
