179-375 9.62e-34

C-terminal catalytic domain of the oxygenase alpha subunit of Rieske-type non-heme iron aromatic ring-hydroxylating oxygenases; C-terminal catalytic domain of the oxygenase alpha subunit of Rieske-type non-heme iron aromatic ring-hydroxylating oxygenase (RHO) family. RHOs, also known as aromatic ring hydroxylating dioxygenases, utilize non-heme Fe(II) to catalyze the addition of hydroxyl groups to the aromatic ring, an initial step in the oxidative degradation of aromatic compounds. RHOs are composed of either two or three protein components, and are comprised of an electron transport chain (ETC), and an oxygenase. The ETC transfers reducing equivalents from the electron donor to the oxygenase component, which in turn transfers electrons to the oxygen molecules. The oxygenase components are oligomers, either (alpha)n or (alpha)n(beta)n. The alpha subunits are the catalytic components and have an N-terminal domain, which binds a Rieske-like 2Fe-2S cluster, and a C-terminal domain which binds the non-heme Fe(II). The Fe(II) is co-ordinated by conserved His and Asp residues. Oxygenases belonging to this family include the alpha subunits of Pseudomonas resinovorans strain CA10 anthranilate 1,2-dioxygenase, Stenotrophomonas maltophilia dicamba O-demethylase, Ralstonia sp. U2 salicylate-5-hydroxylase, Cycloclasticus sp. strain A5 polycyclic aromatic hydrocarbon dioxygenase, toluene 2,3-dioxygenase from Pseudomonas putida F1, dioxin dioxygenase of Sphingomonas sp. Strain RW1, plant choline monooxygenase, and the polycyclic aromatic hydrocarbon (PAH)-degrading ring-hydroxylating dioxygenase from Sphingomonas CHY-1. This group also includes the C-terminal catalytic domains of MupW, part of the mupirocin biosynthetic gene cluster in Pseudomonas fluorescens, and Pseudomonas aeruginosa GbcA (glycine betaine catabolism A). This family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket.

41-156 3.65e-29

Rieske non-heme iron oxygenase (RO) family, N-terminal Rieske domain of the oxygenase alpha subunit; The RO family comprise a large class of aromatic ring-hydroxylating dioxygenases found predominantly in microorganisms. These enzymes enable microorganisms to tolerate and even exclusively utilize aromatic compounds for growth. ROs consist of two or three components: reductase, oxygenase, and ferredoxin (in some cases) components. The oxygenase component may contain alpha and beta subunits, with the beta subunit having a purely structural function. Some oxygenase components contain only an alpha subunit. The oxygenase alpha subunit has two domains, an N-terminal Rieske domain with an [2Fe-2S] cluster and a C-terminal catalytic domain with a mononuclear Fe(II) binding site. The Rieske [2Fe-2S] cluster accepts electrons from the reductase or ferredoxin component and transfers them to the mononuclear iron for catalysis. Reduced pyridine nucleotide is used as the initial source of two electrons for dioxygen activation.

C-terminal catalytic domain of plant choline monooxygenase (CMO) and related aromatic ring hydroxylating dioxygenases; C-terminal catalytic domain of plant choline monooxygenase and related Rieske-type non-heme iron aromatic ring-hydroxylating oxygenases (RHOs, also known as aromatic ring hydroxylating dioxygenases). RHOs utilize non-heme Fe(II) to catalyze the addition of hydroxyl groups to the aromatic ring, an initial step in the oxidative degradation of aromatic compounds. RHOs are composed of either two or three protein components, and are comprised of an electron transport chain (ETC) and an oxygenase. The ETC transfers reducing equivalents from the electron donor to the oxygenase component, which in turn transfers electrons to the oxygen molecules. The oxygenase components are oligomers, either (alpha)n or (alpha)n(beta)n. The alpha subunits are the catalytic components and have an N-terminal domain, which binds a Rieske-like 2Fe-2S cluster, and a C-terminal domain which binds the non-heme Fe(II). The Fe(II) is co-ordinated by conserved His and Asp residues. Plant choline monooxygenase catalyzes the first step in a two-step oxidation of choline to the osmoprotectant glycine betaine. This subfamily belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket.

20-128 1.69e-12

Rieske non-heme iron oxygenase (RO) family, Ortho-halobenzoate-1,2-dioxygenase (OHBDO)-like subfamily, N-terminal Rieske domain of the oxygenase alpha subunit; composed of the oxygenase alpha subunits of OHBDO, salicylate 5-hydroxylase (S5H), terephthalate 1,2-dioxygenase system (TERDOS) and similar proteins. ROs comprise a large class of aromatic ring-hydroxylating dioxygenases that enable microorganisms to tolerate and utilize aromatic compounds for growth. The oxygenase alpha subunit contains an N-terminal Rieske domain with an [2Fe-2S] cluster and a C-terminal catalytic domain with a mononuclear Fe(II) binding site. The Rieske [2Fe-2S] cluster accepts electrons from a reductase or ferredoxin component and transfers them to the mononuclear iron for catalysis. OHBDO converts 2-chlorobenzoate (2-CBA) to catechol as well as 2,4-dCBA and 2,5-dCBA to 4-chlorocatechol, as part of the chlorobenzoate degradation pathway. Although ortho-substituted chlorobenzoates appear to be particularly recalcitrant to biodegradation, several strains utilize 2-CBA and the dCBA derivatives as a sole carbon and energy source. S5H converts salicylate (2-hydroxybenzoate), a metabolic intermediate of phenanthrene, to gentisate (2,5-dihydroxybenzoate) as part of an alternate pathway for naphthalene catabolism. S5H is a multicomponent enzyme made up of NagGH (the oxygenase components), NagAa (the ferredoxin reductase component), and NagAb (the ferredoxin component). The oxygenase component is made up of alpha (NagG) and beta (NagH) subunits. TERDOS is present in gram-positive bacteria and proteobacteria where it converts terephthalate (1,4-dicarboxybenzene) to protocatechuate as part of the terephthalate degradation pathway. The oxygenase component of TERDOS, called TerZ, is a hetero-hexamer with 3 alpha (TerZalpha) and 3 beta (TerZbeta) subunits.

42-128 1.81e-10

Rieske non-heme iron oxygenase (RO) family, Nathphalene 1,2-dioxygenase (NDO) subfamily, N-terminal Rieske domain of the oxygenase alpha subunit; ROs comprise a large class of aromatic ring-hydroxylating dioxygenases that enable microorganisms to tolerate and utilize aromatic compounds for growth. The oxygenase alpha subunit contains an N-terminal Rieske domain with an [2Fe-2S] cluster and a C-terminal catalytic domain with a mononuclear Fe(II) binding site. The Rieske [2Fe-2S] cluster accepts electrons from a reductase or ferredoxin component and transfers them to the mononuclear iron for catalysis. NDO is a three-component RO system consisting of a reductase, a ferredoxin, and a hetero-hexameric alpha-beta subunit oxygenase component. NDO catalyzes the oxidation of naphthalene to cis-(1R,2S)-dihydroxy-1,2-dihydronaphthalene (naphthalene cis-dihydrodiol) with the consumption of O2 and NAD(P)H. NDO has a relaxed substrate specificity and can oxidize almost 100 substrates. Included in its varied activities are the enantiospecific cis-dihydroxylation of polycyclic aromatic hydrocarbons and benzocycloalkenes, benzylic hydroxylation, N- and O-dealkylation, sulfoxidation and desaturation reactions.

42-128 1.17e-08

Rieske domain; a [2Fe-2S] cluster binding domain commonly found in Rieske non-heme iron oxygenase (RO) systems such as naphthalene and biphenyl dioxygenases, as well as in plant/cyanobacterial chloroplast b6f and mitochondrial cytochrome bc(1) complexes. The Rieske domain can be divided into two subdomains, with an incomplete six-stranded, antiparallel beta-barrel at one end, and an iron-sulfur cluster binding subdomain at the other. The Rieske iron-sulfur center contains a [2Fe-2S] cluster, which is involved in electron transfer, and is liganded to two histidine and two cysteine residues present in conserved sequences called Rieske motifs. In RO systems, the N-terminal Rieske domain of the alpha subunit acts as an electron shuttle that accepts electrons from a reductase or ferredoxin component and transfers them to the mononuclear iron in the alpha subunit C-terminal domain to be used for catalysis.

41-128 8.70e-05

This alignment model represents the N-terminal rieske domain of the oxygenase alpha subunit (DitA) of diterpenoid dioxygenase (DTDO). DTDO is a novel aromatic-ring-hydroxylating dioxygenase found in Pseudomonas and other proteobacteria that degrades dehydroabietic acid (DhA). Specifically, DitA hydroxylates 7-oxodehydroabietic acid to 7-oxo-11,12-dihydroxy-8, 13-abietadien acid. The ditA1 and ditA2 genes encode the alpha and beta subunits of the oxygenase component of DTDO while the ditA3 gene encodes the ferredoxin component of DTDO. The organization of the genes encoding the various diterpenoid dioxygenase components, the phylogenetic distinctiveness of both the alpha subunit and the ferredoxin component, and the unusual iron-sulfur cluster of the ferredoxin all suggest that this enzyme belongs to a new class of aromatic ring-hydroxylating dioxygenases.

AIFL (apoptosis-inducing factor like) family, N-terminal Rieske domain; members of this family show similarity to human AIFL, containing an N-terminal Rieske domain and a C-terminal pyridine nucleotide-disulfide oxidoreductase domain (Pyr_redox). The Rieske domain is a [2Fe-2S] cluster binding domain involved in electron transfer. AIFL shares 35% homology with human AIF (apoptosis-inducing factor), mainly in the Pyr_redox domain. AIFL is predominantly localized to the mitochondria. AIFL induces apoptosis in a caspase-dependent manner.
