2-Nitropropane dioxygenase (NPD), one of the nitroalkane oxidizing enzyme families, catalyzes oxidative denitrification of nitroalkanes to their corresponding carbonyl compounds and nitrites. NDP is a member of the NAD(P)H-dependent flavin oxidoreductase 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.

Nitronate monooxygenase; Nitronate monooxygenase (NMO), formerly referred to as 2-nitropropane dioxygenase (NPD) (EC:1.13.11.32), is an FMN-dependent enzyme that uses molecular oxygen to oxidize (anionic) alkyl nitronates and, in the case of the enzyme from Neurospora crassa, (neutral) nitroalkanes to the corresponding carbonyl compounds and nitrite. Previously classified as 2-nitropropane dioxygenase, but it is now recognized that this was the result of the slow ionization of nitroalkanes to their nitronate (anionic) forms. The enzymes from the fungus Neurospora crassa and the yeast Williopsis saturnus var. mrakii (formerly classified as Hansenula mrakii) contain non-covalently bound FMN as the cofactor. Active towards linear alkyl nitronates of lengths between 2 and 6 carbon atoms and, with lower activity, towards propyl-2-nitronate. The enzyme from N. crassa can also utilize neutral nitroalkanes, but with lower activity. One atom of oxygen is incorporated into the carbonyl group of the aldehyde product. The reaction appears to involve the formation of an enzyme-bound nitronate radical and an a-peroxynitroethane species, which then decomposes, either in the active site of the enzyme or after release, to acetaldehyde and nitrite.

TIM barrel proteins share a structurally conserved phosphate binding motif and in general share an eight beta/alpha closed barrel structure. Specific for this family is the conserved phosphate binding site at the edges of strands 7 and 8. The phosphate comes either from the substrate, as in the case of inosine monophosphate dehydrogenase (IMPDH), or from ribulose-5-phosphate 3-epimerase (RPE) or from cofactors, like FMN.

Class I aldolases; Class I aldolases. The class I aldolases use an active-site lysine which stabilizes a reaction intermediates via Schiff base formation, and have TIM beta/alpha barrel fold. The members of this family include 2-keto-3-deoxy-6-phosphogluconate (KDPG) and 2-keto-4-hydroxyglutarate (KHG) aldolases, transaldolase, dihydrodipicolinate synthase sub-family, Type I 3-dehydroquinate dehydratase, DeoC and DhnA proteins, and metal-independent fructose-1,6-bisphosphate aldolase. Although structurally similar, the class II aldolases use a different mechanism and are believed to have an independent evolutionary origin.

2-Nitropropane dioxygenase (NPD)-like domain, associated with the (acyl-carrier-protein) S-malonyltransferase FabD. NPD is part of the nitroalkaneoxidizing enzyme family, that catalyzes oxidative denitrification of nitroalkanes to their corresponding carbonyl compounds and nitrites. NDPs are members of the NAD(P)H-dependent flavin oxidoreductase 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.

IMPDH: The catalytic domain of the inosine monophosphate dehydrogenase. IMPDH catalyzes the NAD-dependent oxidation of inosine 5'-monophosphate (IMP) to xanthosine 5' monophosphate (XMP). It is a rate-limiting step in the de novo synthesis of the guanine nucleotides. There is often a CBS domain inserted in the middle of this domain, which is proposed to play a regulatory role. IMPDH is a key enzyme in the regulation of cell proliferation and differentiation. It has been identified as an attractive target for developing chemotherapeutic agents.

1.16e-04
Family of homologous FMN-dependent alpha-hydroxyacid oxidizing enzymes. This family occurs in both prokaryotes and eukaryotes. Members of this family include flavocytochrome b2 (FCB2), glycolate oxidase (GOX), lactate monooxygenase (LMO), mandelate dehydrogenase (MDH), and long chain hydroxyacid oxidase (LCHAO). In green plants, glycolate oxidase is one of the key enzymes in photorespiration where it oxidizes glycolate to glyoxylate. LMO catalyzes the oxidation of L-lactate to acetate and carbon dioxide. MDH oxidizes (S)-mandelate to phenylglyoxalate. It is an enzyme in the mandelate pathway that occurs in several strains of Pseudomonas which converts (R)-mandelate to benzoate.

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.
