4-308 6.35e-127

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.

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.

2-280 1.28e-55

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. [Unknown function, General]

4-308 6.35e-127

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.

The enzymatic mechanism of 1VHN is not known at the present.

2-280 1.28e-55

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. [Unknown function, General]

124-233 1.05e-10

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.

Archeal FMN-binding domain. This family of archaeal proteins are part of the NAD(P)H-dependent flavin oxidoreductase (oxidored) FMN-binding family that reduce a range of alternative electron acceptors. Most use FAD/FMN as a cofactor and NAD(P)H as electron donor. Some contain 4Fe-4S cluster to transfer electron from FAD to FMN. The specific function of this group is unknown.

123-233 3.30e-09

Old yellow enzyme (OYE) YqjM-like FMN binding domain. YqjM is involved in the oxidative stress response of Bacillus subtilis. Like the other OYE members, each monomer of YqjM contains FMN as a non-covalently bound cofactor and uses NADPH as a reducing agent. The YqjM enzyme exists as a homotetramer that is assembled as a dimer of catalytically dependent dimers, while other OYE members exist only as monomers or dimers. Moreover, the protein displays a shared active site architecture where an arginine finger at the COOH terminus of one monomer extends into the active site of the adjacent monomer and is directly involved in substrate recognition. Another remarkable difference in the binding of the ligand in YqjM is represented by the contribution of the NH2-terminal tyrosine instead of a COOH-terminal tyrosine in OYE and its homologs.

78-229 8.46e-07

Dihydroorotate dehydrogenase (DHOD) and Dihydropyrimidine dehydrogenase (DHPD) 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. DHPD catalyzes the first step in pyrimidine degradation: the NADPH-dependent reduction of uracil and thymine to the corresponding 5,6-dihydropyrimidines. DHPD contains two FAD, two FMN and eight [4Fe-4S] clusters, arranged in two electron transfer chains that pass its homodimeric interface twice. Two of the Fe-S clusters show a hitherto unobserved coordination involving a glutamine residue.

N-acetylmannosamine-6-phosphate epimerase (NanE) converts N-acetylmannosamine-6-phosphate to N-acetylglucosamine-6-phosphate. This reaction is part of the pathway that allows the usage of sialic acid as a carbohydrate source. Sialic acids are a family of related sugars that are found as a component of glycoproteins, gangliosides, and other sialoglycoconjugates.
