Type 1 glutamine amidotransferase (GATase1)-like domain found in Human DJ-1; Type 1 glutamine amidotransferase (GATase1)-like domain found in Human DJ-1. DJ-1 is involved in multiple physiological processes including cancer, Parkinson's disease and male fertility. It is unclear how DJ-1 functions in these. DJ-1 has been shown to possess chaperone activity. DJ-1 is preferentially expressed in the testis and moderately in other tissues; it is induced together with genes involved in oxidative stress response. The Drosophila homologue (DJ-1A) plays an essential role in oxidative stress response and neuronal maintenance. Inhibition of DJ-1A function through RNAi, results in the cellular accumulation of reactive oxygen species, organismal hypersensitivity to oxidative stress, and dysfunction and degeneration of dopaminergic and photoreceptor neurons. DJ-1 has lacks enzymatic activity and the catalytic triad of typical GATase1 domains, however it does contain the highly conserved cysteine located at the nucelophile elbow region typical of these domains. This cysteine been proposed to be a site of regulation of DJ-1 activity by oxidation. DJ-1 is a dimeric enzyme. Pssm-ID: 153229 [Multi-domain] Cd Length: 163 Bit Score: 98.01 E-value: 3.03e-26

This group includes EcHsp31 and Saccharomyces cerevisiae Ydr533c protein. EcHsp31 has chaperone activity. Ydr533c is upregulated in response to various stress conditions along with the heat shock family. EcHsp31 coordinates a metal ion using a 2-His-1-carboxylate motif present in various ions that use iron as a cofactor such as Carboxypeptidase A. The catalytic triad typical of GATase1 domains is not conserved in this GATase1-like domain. However, in common with a typical GATase1 domain, a reactive Cys residue is found in the sharp turn between a beta strand and an alpha helix termed the nucleophile elbow. For EcHsp31, this Cys together with a different His and, an Asp (rather than a Glu) residue form a different catalytic triad from the typical GATase1 domain. For Ydr533c a catalytic triad forms from the conserved Cys together with a different His and Glu from that of the typical GATase1domain. Ydr533c protein and EcHsp31 are homodimers.

Small chain of the glutamine-dependent form of carbamoyl phosphate synthase, CPSase II; This group of sequences represents the small chain of the glutamine-dependent form of carbamoyl phosphate synthase, CPSase II. CPSase II catalyzes the production of carbomyl phosphate (CP) from bicarbonate, glutamine and two molecules of MgATP. The reaction is believed to proceed by a series of four biochemical reactions involving a minimum of three discrete highly reactive intermediates. The synthesis of CP is critical for the initiation of two separate biosynthetic pathways. In one CP is coupled to aspartate, its carbon and nitrogen nuclei ultimately incorporated into the aromatic moieties of pyrimidine nucleotides. In the second pathway CP is condensed with ornithine at the start of the urea cycle and is utilized for the detoxification of ammonia and biosynthesis of arginine. CPSases may be encoded by one or by several genes, depending on the species. The E.coli enzyme is a heterodimer consisting of two polypeptide chains referred to as the small and large subunit. Ammonia an intermediate during the biosynthesis of carbomyl phosphate produced by the hydrolysis of glutamine in the small subunit of the enzyme is delivered via a molecular tunnel between the remotely located carboxyphosphate active site in the large subunit. CPSase IIs belong to the triad family of amidotransferases having a conserved Cys-His-Glu catalytic triad in the glutaminase active site. This group also contains the sequence from the mammalian urea cycle form which has lost the active site Cys, resulting in an ammonia-dependent form, CPSase I.

Type 1 glutamine amidotransferase (GATase1)-like domain found in Saccharomyces cerevisiae Ydr533c protein; Type 1 glutamine amidotransferase (GATase1)-like domain found in Saccharomyces cerevisiae Ydr533c protein. This group includes proteins similar to S. cerevisiae Ydr533c. Ydr533c is upregulated in response to various stress conditions along with the heat shock family. The catalytic triad typical of GATase1domains is not conserved in this GATase1-like domain. However, in common with a typical GATase1domain, a reactive Cys residue is found in the sharp turn between a beta strand and an alpha helix termed the nucleophile elbow. This Cys together with a different His and Glu residue form a different catalytic triad from the typical GATase1domain. Ydr533c protein is a homodimer.

Type 1 glutamine amidotransferase (GATase1)-like domain found in at the C-terminal of several large catalases; Type 1 glutamine amidotransferase (GATase1)-like domain found in at the C-terminal of several large catalases. Catalase catalyzes the dismutation of hydrogen peroxide (H2O2) to water and oxygen. This group includes the large catalases: Neurospora crassa Catalase-1 and Catalase-3 and, Escherichia coli HP-II. This GATase1-like domain has an essential role in HP-II catalase activity. However, it lacks enzymatic activity and the catalytic triad typical of GATase1 domains. Catalase-1 and -3 are homotetrameric, HP-II is homohexameric. It has been proposed that this domain may facilitate the folding and oligomerization process. The interface between this GATase1-like domain of HP-II and the core of the subunit forms part of a channel which provides access to the deeply buried catalase active sites of HPII. Catalase-1 is associated with non-growing cells; Catalase-3 is associated with growing conditions. HP-II is produced in stationary phase. Catalase-1 is induced by ethanol and heat shock. Catalase-3 is induced under stress conditions such a hydrogen peroxide, paraquat, cadmium, heat shock, uric acid and nitrate treatment.
