 102-227 8.66e-95

Iron-sulfur protein (ISP) component of the b6f complex family, Rieske domain; The Rieske domain is a [2Fe-2S] cluster binding domain involved in electron transfer. The cytochrome b6f complex from Mastigocladus laminosus, a thermophilic cyanobacterium, contains four large subunits, including cytochrome f, cytochrome b6, the Rieske ISP, and subunit IV; as well as four small hydrophobic subunits, PetG, PetL, PetM, and PetN. Rieske ISP, one of the large subunits of the cytochrome bc-type complexes, is involved in respiratory and photosynthetic electron transfer. The core of the chloroplast b6f complex is similar to the analogous respiratory cytochrome bc(1) complex, but the domain arrangement outside the core and the complement of prosthetic groups are strikingly different.

The model excludes the Rieske iron-sulfur protein as found in the cytochrome b6-f complex of the Cyanobacteria and chloroplasts. Most members of this family have a recognizable twin-arginine translocation (tat) signal sequence (DeltaPh-dependent translocation in chloroplast) for transport across the membrane with the 2Fe-2S group already bound. These signal sequences include a motif resembling RRxFLK before the transmembrane helix. [Energy metabolism, Electron transport]

Rieske [2Fe-2S] domain; The rieske domain has a [2Fe-2S] centre. Two conserved cysteines coordinate one Fe ion, while the other Fe ion is coordinated by two conserved histidines. In hyperthermophilic archaea there is a SKTPCX(2-3)C motif at the C-terminus. The cysteines in this motif form a disulphide bridge, which stabilizes the protein.

YhfW family, C-terminal Rieske domain; YhfW is a protein of unknown function with an N-terminal DadA-like (glycine/D-amino acid dehydrogenase) domain and a C-terminal Rieske domain. The Rieske domain is a [2Fe-2S] cluster binding domain involved in electron transfer. It is 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. YhfW is found in bacteria, some eukaryotes and archaea.

Iron-sulfur protein (ISP) component of the bc(1) complex family, Rieske domain; The Rieske domain is a [2Fe-2S] cluster binding domain involved in electron transfer. The bc(1) complex is a multisubunit enzyme found in many different organisms including uni- and multi-cellular eukaryotes, plants (in their mitochondria) and bacteria. The cytochrome bc(1) and b6f complexes are central components of the respiratory and photosynthetic electron transport chains, respectively, which carry out similar core electron and proton transfer steps. The bc(1) and b6f complexes share a common core structure of three catalytic subunits: cyt b, the Rieske ISP, and either a cyt c1 in the bc(1) complex or cyt f in the b6f complex, which are arranged in an integral membrane-bound dimeric complex. While the core of the b6f complex is similar to that of the bc(1) complex, the domain arrangement outside the core and the complement of prosthetic groups are strikingly different.

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.

Rieske [2Fe-2S] domain; The rieske domain has a [2Fe-2S] centre. Two conserved cysteines coordinate one Fe ion, while the other Fe ion is coordinated by two conserved histidines. In hyperthermophilic archaea there is a SKTPCX(2-3)C motif at the C-terminus. The cysteines in this motif form a disulphide bridge, which stabilizes the protein.

 151-207 9.30e-07

Small subunit of Arsenite oxidase (ArOX) family, Rieske domain; ArOX is a molybdenum/iron protein involved in the detoxification of arsenic, oxidizing it to arsenate. It consists of two subunits, a large subunit similar to members of the DMSO reductase family of molybdenum enzymes and a small subunit with a Rieske-type [2Fe-2S] cluster. The large subunit of ArOX contains the molybdenum site at which the oxidation of arsenite occurs. The small subunit contains a domain homologous to the Rieske domains of the cytochrome bc(1) and cytochrome b6f complexes as well as naphthalene 1,2-dioxygenase. The Rieske domain is a [2Fe-2S] cluster binding domain involved in electron transfer.

 85-205 1.96e-05

SoxF and SoxL family, Rieske domain; The Rieske domain is a [2Fe-2S] cluster binding domain involved in electron transfer. SoxF is a subunit of the terminal oxidase supercomplex SoxM in the plasma membrane of Sulfolobus acidocaldarius that combines features of a cytochrome bc(1) complex and a cytochrome. The Rieske domain of SoxF has a 12 residue insertion which is not found in eukaryotic and bacterial Rieske proteins and is thought to influence the redox properties of the iron-sulfur cluster. SoxL is a Rieske protein which may be part of an archaeal bc-complex homologue whose physiological function is still unknown. SoxL has two features not seen in other Rieske proteins; (i) a significantly greater distance between the two cluster-binding sites and (ii) an unexpected Pro -> Asp substitution at one of the cluster binding sites. SoxF and SoxL are found in archaea and in bacteria.

 151-210 2.98e-05

arsenite oxidase, small subunit; This model represents the small subunit of an arsenite oxidase complex. It is a Rieske protein and appears to rely on the Tat (twin-arginine translocation) system to cross the membrane. Although this enzyme could run in the direction of arsenate reduction to arsenite in principle, the relevant biological function is arsenite oxidation for energy metabolism, not arsenic resistance. Homologs to both large (TIGR02693) and small subunits that score in the gray zone between the set trusted and noise bit score cutoffs for the respective models are found in Aeropyrum pernix K1 and in Sulfolobus tokodaii str. 7.

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.
