25-266 6.48e-85

Dihydrouridine synthase-like (DUS-like) FMN-binding domain. Members of this family catalyze the reduction of the 5,6-double bond of a uridine residue on tRNA. Dihydrouridine modification of tRNA is widely observed in prokaryotes and eukaryotes, and also in some archaea. Most dihydrouridines are found in the D loop of t-RNAs. The role of dihydrouridine in tRNA is currently unknown, but may increase conformational flexibility of the tRNA. It is likely that different family members have different substrate specificities, which may overlap. 1VHN, a putative flavin oxidoreductase, has high sequence similarity to DUS. The enzymatic mechanism of 1VHN is not known at the present.

27-275 1.88e-45

Dihydrouridine synthase (Dus); Members of this family catalyze the reduction of the 5,6-double bond of a uridine residue on tRNA. Dihydrouridine modification of tRNA is widely observed in prokaryotes and eukaryotes, and also in some archae. Most dihydrouridines are found in the D loop of t-RNAs. The role of dihydrouridine in tRNA is currently unknown, but may increase conformational flexibility of the tRNA. It is likely that different family members have different substrate specificities, which may overlap. Dus 1 from Saccharomyces cerevisiae acts on pre-tRNA-Phe, while Dus 2 acts on pre-tRNA-Tyr and pre-tRNA-Leu. Dus 1 is active as a single subunit, requiring NADPH or NADH, and is stimulated by the presence of FAD. Some family members may be targeted to the mitochondria and even have a role in mitochondria.

23-265 2.78e-35

putative TIM-barrel protein, nifR3 family; This model represents one branch of COG0042 (Predicted TIM-barrel enzymes, possibly dehydrogenases, nifR3 family). This branch includes NifR3 itself, from Rhodobacter capsulatus. It excludes a broadly distributed but more sparsely populated subfamily that contains sll0926 from Synechocystis PCC6803, HI0634 from Haemophilus influenzae, and BB0225 from Borrelia burgdorferi. It also excludes a shorter and more distant archaeal subfamily.The function of nifR3, a member of this family, is unknown, but it is found in an operon with nitrogen-sensing two component regulators in Rhodobacter capsulatus.Members of this family show a distant relationship to alpha/beta (TIM) barrel enzymes such as dihydroorotate dehydrogenase and glycolate oxidase.

395-457 7.98e-10

Double-stranded RNA binding motif; Sequences gathered for seed by HMM_iterative_training Putative motif shared by proteins that bind to dsRNA. At least some DSRM proteins seem to bind to specific RNA targets. Exemplified by Staufen, which is involved in localization of at least five different mRNAs in the early Drosophila embryo. Also by interferon-induced protein kinase in humans, which is part of the cellular response to dsRNA.

25-266 6.48e-85

Dihydrouridine synthase-like (DUS-like) FMN-binding domain. Members of this family catalyze the reduction of the 5,6-double bond of a uridine residue on tRNA. Dihydrouridine modification of tRNA is widely observed in prokaryotes and eukaryotes, and also in some archaea. Most dihydrouridines are found in the D loop of t-RNAs. The role of dihydrouridine in tRNA is currently unknown, but may increase conformational flexibility of the tRNA. It is likely that different family members have different substrate specificities, which may overlap. 1VHN, a putative flavin oxidoreductase, has high sequence similarity to DUS. The enzymatic mechanism of 1VHN is not known at the present.

Dihydrouridine synthase (Dus); Members of this family catalyze the reduction of the 5,6-double bond of a uridine residue on tRNA. Dihydrouridine modification of tRNA is widely observed in prokaryotes and eukaryotes, and also in some archae. Most dihydrouridines are found in the D loop of t-RNAs. The role of dihydrouridine in tRNA is currently unknown, but may increase conformational flexibility of the tRNA. It is likely that different family members have different substrate specificities, which may overlap. Dus 1 from Saccharomyces cerevisiae acts on pre-tRNA-Phe, while Dus 2 acts on pre-tRNA-Tyr and pre-tRNA-Leu. Dus 1 is active as a single subunit, requiring NADPH or NADH, and is stimulated by the presence of FAD. Some family members may be targeted to the mitochondria and even have a role in mitochondria.

23-265 2.78e-35

putative TIM-barrel protein, nifR3 family; This model represents one branch of COG0042 (Predicted TIM-barrel enzymes, possibly dehydrogenases, nifR3 family). This branch includes NifR3 itself, from Rhodobacter capsulatus. It excludes a broadly distributed but more sparsely populated subfamily that contains sll0926 from Synechocystis PCC6803, HI0634 from Haemophilus influenzae, and BB0225 from Borrelia burgdorferi. It also excludes a shorter and more distant archaeal subfamily.The function of nifR3, a member of this family, is unknown, but it is found in an operon with nitrogen-sensing two component regulators in Rhodobacter capsulatus.Members of this family show a distant relationship to alpha/beta (TIM) barrel enzymes such as dihydroorotate dehydrogenase and glycolate oxidase.

double-stranded RNA binding motif of tRNA-dihydrouridine(20) synthase [NAD(P)+]-like (DUS2L) and similar proteins; DUS2L (also known as dihydrouridine synthase 2 (DUS2), up-regulated in lung cancer protein 8 (URLC8), or tRNA-dihydrouridine synthase 2-like) catalyzes the synthesis of dihydrouridine, a modified base found in the D-loop of most tRNAs. It negatively regulates the activation of EIF2AK2/PKR. DUS2L contains an N-terminal FMN-binding domain and a C-terminal double-stranded RNA binding motif (DSRM) that is not sequence specific, but highly specific for dsRNAs of various origin and structure.

Double-stranded RNA binding motif; Sequences gathered for seed by HMM_iterative_training Putative motif shared by proteins that bind to dsRNA. At least some DSRM proteins seem to bind to specific RNA targets. Exemplified by Staufen, which is involved in localization of at least five different mRNAs in the early Drosophila embryo. Also by interferon-induced protein kinase in humans, which is part of the cellular response to dsRNA.

109-281 1.45e-07

Dihydroorotate dehydrogenase (DHOD) class 1B FMN-binding domain. DHOD catalyzes the oxidation of (S)-dihydroorotate to orotate. This is the fourth step and the only redox reaction in the de novo biosynthesis of UMP, the precursor of all pyrimidine nucleotides. DHOD requires FMN as co-factor. DHOD divides into class 1 and class 2 based on their amino acid sequences and cellular location. Members of class 1 are cytosolic enzymes and multimers while class 2 enzymes are membrane associated and monomeric. The class 1 enzymes can be further divided into subtypes 1A and 1B which are homodimers and heterotetrameric proteins, respectively.

402-454 1.87e-06

double-stranded RNA binding motif (DSRM) superfamily; DSRM (also known as dsRBM) is a 65-70 amino acid domain that adopts an alpha-beta-beta-beta-alpha fold. It is not sequence specific, but highly specific for double-stranded RNAs (dsRNAs) of various origin and structure. The DSRM domains are found in a variety of proteins including dsRNA dependent protein kinase PKR, RNA helicases, Drosophila Staufen protein, E. coli RNase III, RNase H1, and dsRNA dependent adenosine deaminases. They are involved in numerous cellular mechanisms ranging from localization and transport of messenger RNAs, through maturation and degradation of RNAs, to viral response and signal transduction. Some members harbor tandem DSRMs that act in small RNA biogenesis.

Old yellow enzyme (OYE)-like FMN binding domain. OYE was the first flavin-dependent enzyme identified, however its true physiological role remains elusive to this day. Each monomer of OYE contains FMN as a non-covalently bound cofactor, uses NADPH as a reducing agent with oxygens, quinones, and alpha,beta-unsaturated aldehydes and ketones, and can act as electron acceptors in the catalytic reaction. Members of OYE family include trimethylamine dehydrogenase, 2,4-dienoyl-CoA reductase, enoate reductase, pentaerythriol tetranitrate reductase, xenobiotic reductase, and morphinone reductase.

double-stranded RNA binding motif of ribonuclease III (RNase III) and similar proteins; RNase III (EC 3.1.26.3; also known as ribonuclease 3) digests double-stranded RNA formed within single-strand substrates, but not RNA-DNA hybrids. It is involved in the processing of rRNA precursors, viral transcripts, some mRNAs, and at least 1 tRNA (metY, a minor form of tRNA-init-Met). It cleaves the 30S primary rRNA transcript to yield the immediate precursors to the 16S and 23S rRNAs. The cleavage can occur in assembled 30S, 50S, and even 70S subunits and is influenced by the presence of ribosomal proteins. The RNase III family also includes the mitochondrion-specific ribosomal protein mL44 subfamily, which is composed of mitochondrial 54S ribosomal protein L3 (MRPL3) and mitochondrial 39S ribosomal protein L44 (MRPL44). Members of this family contain an RNase III domain and a C-terminal double-stranded RNA binding motif (DSRM). DSRM is not sequence specific, but highly specific for dsRNAs of various origin and structure.

211-264 1.57e-03

The cyclase subunit of imidazoleglycerol phosphate synthase (HisF). Imidazole glycerol phosphate synthase (IGPS) catalyzes the fifth step of histidine biosynthesis, the formation of the imidazole ring. IGPS converts N1-(5'-phosphoribulosyl)-formimino-5-aminoimidazole-4-carboxamide ribonucleotide (PRFAR) to imidazole glycerol phosphate (ImGP) and 5'-(5-aminoimidazole-4-carboxamide) ribonucleotide (AICAR). This conversion involves two tightly coupled reactions in distinct active sites of IGPS. The two catalytic domains can be fused, like in fungi and plants, or peformed by a heterodimer (HisH-glutaminase and HisF-cyclase), like in bacteria.
