C-terminal domain of GMP synthetase (glutamine-hydrolyzing); The C-terminal domain of GMP synthetase (glutamine-hydrolyzing, EC 6.3.5.2) contains two subdomains: the ATP pyrophosphatase domain at the N-terminal and the dimerization domain at the C-terminal end. The ATP-PPase domain is a twisted, five-stranded parallel beta-sheet sandwiched between helical layers. It has a signature nucleotide-binding motif, or PP-loop, at the end of the first-beta strand. GMP synthetase is a homodimer, but in some archaea, it is a heterodimer made up of ATP pyrophosphatase (ATP-PPase) and a GATase subunit. In eukaryotes and bacteria, the two catalytic units are encoded by a single gene producing a two-domain-type GMP with a GATase domain in the N-terminus and an ATP-PPase domain in the C-terminus.

Subgroup of proteins having the Type 1 glutamine amidotransferase (GATase1) domain; This group contains a subgroup of proteins having the Type 1 glutamine amidotransferase (GATase1) domain. GATase activity catalyses the transfer of ammonia from the amide side chain of glutamine to an acceptor substrate. Glutamine amidotransferases (GATase) includes the triad family of amidotransferases which have a conserved Cys-His-Glu catalytic triad in the glutaminase active site. In this subgroup this triad is conserved. GATase activity can be found in a range of biosynthetic enzymes, including: glutamine amidotransferase, formylglycinamide ribonucleotide, GMP synthetase , anthranilate synthase component II, glutamine-dependent carbamoyl phosphate synthase, cytidine triphosphate synthetase, gamma-glutamyl hydrolase, imidazole glycerol phosphate synthase and, cobyric acid synthase. Glutamine amidotransferase (GATase) domains can occur either as single polypeptides, as in glutamine amidotransferases, or as domains in a much larger multifunctional synthase protein, such as CPSase.

Type 1 glutamine amidotransferase (GATase1) domain found in Anthranilate synthase; Type 1 glutamine amidotransferase (GATase1) domain found in Anthranilate synthase (ASase). This group contains proteins similar to para-aminobenzoate (PABA) synthase and ASase. These enzymes catalyze similar reactions and produce similar products, PABA and ortho-aminobenzoate (anthranilate). Each enzyme is composed of non-identical subunits: a glutamine amidotransferase subunit (component II) and a subunit that produces an aminobenzoate products (component I). ASase catalyses the synthesis of anthranilate from chorismate and glutamine and is a tetrameric protein comprising two copies each of components I and II. Component II of ASase belongs to the family of triad GTases which hydrolyze glutamine and transfer nascent ammonia between the active sites. In some bacteria, such as Escherichia coli, component II can be much larger than in other organisms, due to the presence of phosphoribosyl-anthranilate transferase (PRTase) activity. PRTase catalyses the second step in tryptophan biosynthesis and results in the addition of 5-phosphoribosyl-1-pyrophosphate to anthranilate to create N-5'-phosphoribosyl-anthranilate. In E.coli, the first step in the conversion of chorismate to PABA involves two proteins: PabA and PabB which co-operate to transfer the amide nitrogen of glutamine to chorismate forming 4-amino-4 deoxychorismate (ADC). PabA acts as a glutamine amidotransferase, supplying an amino group to PabB, which carries out the amination reaction. A third protein PabC then mediates elimination of pyruvate and aromatization to give PABA. Several organisms have bipartite proteins containing fused domains homologous to PabA and PabB commonly called PABA synthases. These hybrid PABA synthases may produce ADC and not PABA.

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.

Lactate racemization operon protein LarE and similar proteins; This subfamily includes Lactiplantibacillus plantarum LarE, a sacrificial sulfur insertase of the N-type ATP pyrophosphatase family. LarE is part of the lar operon, encoding five Lar proteins (LarA-E) that collaboratively synthesize and incorporate a niacin-derived Ni-containing cofactor into LarA, an Ni-dependent lactate racemase. It catalyzes successive thiolation reactions by donating the sulfur atom of their exclusive cysteine residues to the substrate. The LarE-like subfamily belongs to the nucleotide alpha hydrolase (AANH) superfamily that includes N-type ATP PPases and ATP sulfurylases. It forms an alpha/beta/alpha fold which binds to the adenosine group. Proteins from this subfamily probably binds ATP. This domain is about 200 amino acids long with a strongly conserved motif SGGxDS at the N-terminus. Pssm-ID: 467494 [Multi-domain] Cd Length: 222 Bit Score: 46.87 E-value: 9.53e-06

7-cyano-7-deazaguanine synthase QueC and similar proteins; 7-cyano-7-deazaguanine synthase (EC 6.3.4.20) is also called 7-cyano-7-carbaguanine synthase, preQ(0) synthase, or queuosine biosynthesis protein QueC. It catalyzes the ATP-dependent conversion of 7-carboxy-7-deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)), as part of the biosynthesis pathway of queuosine (Q). Q is one of the most complex modifications occurring at the wobble position of tRNAs with GUN anticodons, and is implicated in a number of biological activities, including accuracy of decoding, virulence, and cellular differentiation. This subfamily belongs to the adenine nucleotide alpha hydrolase (AANH) superfamily that also includes other N-type ATP PPases and ATP sulfurylases. It forms an alpha/beta/alpha fold which binds to the adenosine group. Pssm-ID: 467499 [Multi-domain] Cd Length: 208 Bit Score: 44.91 E-value: 3.23e-05

NAD(+) synthase; NAD(+) synthase (EC 6.3.5.1), a homodimer, catalyzes the final step in the de novo nicotinamide adenine dinucleotide (NAD(+)) biosynthesis, an amide transfer from either ammonia or glutamine to nicotinic acid adenine dinucleotide (NaAD). The conversion of NaAD to NAD(+) occurs via a NAD-adenylate intermediate and requires ATP and Mg(2+). The intermediate is subsequently cleaved into NAD(+) and AMP. In many prokaryotes, such as Escherichia coli, NAD synthase consists of a single domain and is strictly ammonia dependent. In contrast, eukaryotes and other prokaryotes have an additional N-terminal amidohydrolase domain that prefer glutamine. Interestingly, NAD(+) synthases in these prokaryotes, can also utilize ammonia as an amide source. Pssm-ID: 467484 [Multi-domain] Cd Length: 248 Bit Score: 42.54 E-value: 2.98e-04

MnmA catalyzes the 2-thiolation of uridine at the wobble position (U34) of tRNA, leading to the formation of s(2)U34. TRMU/MTU1 catalyzes the 2-thiolation of uridine at the wobble position (U34) of mitochondrial tRNA(Lys), tRNA(Glu) and tRNA(Gln); this is required for the formation of 5-taurinomethyl-2-thiouridine (tm5s2U) of mitochondrial tRNA(Lys), tRNA(Glu), and tRNA(Gln) at the wobble position. This family belongs to the adenine nucleotide alpha hydrolase (AANH) superfamily that also includes other N-type ATP PPases and ATP sulfurylases.
