         (264 letters)



>gnl|CDD|99792 cd06195, FNR1, Ferredoxin-NADP+ (oxido)reductase is an
           FAD-containing enzyme that catalyzes the reversible
           electron transfer between NADP(H) and electron carrier
           proteins such as ferredoxin and flavodoxin. Isoforms of
           these flavoproteins (i.e. having a non-covalently bound
           FAD as a prosthetic group) are present in chloroplasts,
           mitochondria, and bacteria in which they participate in
           a wide variety of redox metabolic pathways. The
           C-terminal domain contains most of the NADP(H) binding
           residues and the N-terminal domain interacts
           non-covalently with the isoalloxazine rings of the
           flavin molecule which lies largely in a large gap
           betweed the two domains. Ferredoxin-NADP+ reductase
           first accepts one electron from reduced ferredoxin to
           form a flavin semiquinone intermediate. The enzyme then
           accepts a second electron to form FADH2 which then
           transfers two electrons and a proton to NADP+ to form
           NADPH..

>gnl|CDD|99778 cd00322, FNR_like, Ferredoxin reductase (FNR), an FAD and NAD(P)
           binding protein, was intially identified as a
           chloroplast reductase activity, catalyzing the electron
           transfer from reduced iron-sulfur protein ferredoxin to
           NADP+ as the final step in the electron transport
           mechanism of photosystem I. FNR transfers electrons from
           reduced ferredoxin to FAD (forming FADH2 via a
           semiquinone intermediate) and then transfers a hydride
           ion to convert NADP+ to NADPH. FNR has since been shown
           to utilize a variety of electron acceptors and donors
           and has a variety of physiological functions including
           nitrogen assimilation, dinitrogen fixation, steroid
           hydroxylation, fatty acid metabolism, oxygenase
           activity, and methane assimilation in many organisms.
           FNR has an NAD(P)-binding sub-domain of the alpha/beta
           class and a discrete (usually N-terminal) flavin
           sub-domain which vary in orientation with respect to the
           NAD(P) binding domain. The N-terminal moeity may contain
           a flavin prosthetic group (as in flavoenzymes) or use
           flavin as a substrate. Because flavins such as FAD can
           exist in oxidized, semiquinone (one- electron reduced),
           or fully reduced hydroquinone forms, FNR can interact
           with one and 2 electron carriers. FNR has a strong
           preference for NADP(H) vs NAD(H)..

>gnl|CDD|99784 cd06187, O2ase_reductase_like, The oxygenase reductase FAD/NADH
           binding domain acts as part of the multi-component
           bacterial oxygenases which oxidize hydrocarbons using
           oxygen as the oxidant. Electron transfer is from NADH
           via FAD (in the oxygenase reductase) and an [2FE-2S]
           ferredoxin center (fused to the FAD/NADH domain and/or
           discrete) to the oxygenase. Dioxygenases add both atoms
           of oxygen to the substrate, while mono-oxygenases (aka
           mixed oxygenases) add one atom to the substrate and one
           atom to water. In dioxygenases, Class I enzymes are 2
           component, containing a reductase with Rieske type
           [2Fe-2S] redox centers and an oxygenase. Class II are 3
           component, having discrete flavin and ferredoxin
           proteins and an oxygenase. Class III have 2 [2Fe-2S]
           centers, one fused to the flavin domain and the other
           separate..

>gnl|CDD|99780 cd06183, cyt_b5_reduct_like, Cytochrome b5 reductase catalyzes the
           reduction of 2 molecules of cytochrome b5 using NADH as
           an electron donor. Like ferredoxin reductases, these
           proteins have an N-terminal FAD binding subdomain and a
           C-terminal NADH binding subdomain, separated by a cleft,
           which accepts FAD. The NADH-binding moiety interacts
           with part of the FAD and resembles a Rossmann fold.
           However, NAD is bound differently than in canonical
           Rossmann fold proteins. Nitrate reductases,
           flavoproteins similar to pyridine nucleotide cytochrome
           reductases, catalyze the reduction of nitrate to
           nitrite. The enzyme can be divided into three functional
           fragments that bind the cofactors molybdopterin,
           heme-iron, and FAD/NADH..

           subdomain. Oxygenases oxidize hydrocarbons using

           coli hydroxylate PA-CoA in the second step of PA

           ferredoxin reductase-like domain with an iron-sulfur
           binding cluster domain. Ferredoxins catalyze electron
           transfer between an NAD(P)-binding domain of the
           alpha/beta class and a discrete (usually N-terminal)
           domain which vary in orientation with respect to the
           NAD(P) binding domain. The N-terminal portion may
           contain a flavin prosthetic group, as in flavoenzymes,
           or use flavin as a substrate. Ferredoxin-NADP+
           (oxido)reductase is an FAD-containing enzyme that
           catalyzes the reversible electron transfer between
           NADP(H) and electron carrier proteins such as ferredoxin
           and flavodoxin. Isoforms of these flavoproteins (i.e.
           having a non-covalently bound FAD as a prosthetic group)
           are present in chloroplasts, mitochondria, and bacteria
           and participate in a wide variety of redox metabolic
           pathways. The C-terminal domain contains most of the
           NADP(H) binding residues and the N-terminal domain
           interacts non-covalently with the isoalloxazine rings of
           the flavin molecule which lies largely in a large gap

           first accepts one electron from reduced ferredoxin to

           accepts a second electron to form FADH2 which then

           responsible for the regeneration of methionine from
           homocysteine, as well as the coversion of
           methyltetrahydrofolate to tetrahydrofolate. In MSR,
           electrons are transferred from NADPH to FAD to FMN to
           cob(II)alamin. MSR resembles proteins of the cytochrome
           p450 family including nitric oxide synthase, the alpha
           subunit of sulfite reductase, but contains an extended
           hinge region. NADPH cytochrome p450 reductase (CYPOR)
           serves as an electron donor in several oxygenase systems
           and is a component of nitric oxide synthases and
           methionine synthase reductases. CYPOR transfers two
           electrons from NADPH to the heme of cytochrome p450 via
           FAD and FMN. CYPORs resemble ferredoxin reductase (FNR)
           but have a connecting subdomain inserted within the
           flavin binding region, which helps orient the FMN
           binding doamin with the FNR module. Ferredoxin-NADP+
           (oxido)reductase is an FAD-containing enzyme that
           catalyzes the reversible electron transfer between
           NADP(H) and electron carrier proteins such as ferredoxin
           and flavodoxin. Isoforms of these flavoproteins (i.e.
           having a non-covalently bound FAD as a prosthetic group)
           are present in chloroplasts, mitochondria, and bacteria
           in which they participate in a wide variety of redox
           metabolic pathways. The C-terminal domain contains most
           of the NADP(H) binding residues and the N-terminal
           domain interacts non-covalently with the isoalloxazine
           rings of the flavin molecule which lies largely in a
           large gap betweed the two domains. Ferredoxin-NADP+
           reductase first accepts one electron from reduced
           ferredoxin to form a flavin semiquinone intermediate.
           The enzyme then accepts a second electron to form FADH2
           which then transfers two electrons and a proton to NADP+
           to form NADPH..

>gnl|CDD|99779 cd06182, CYPOR_like, NADPH cytochrome p450 reductase (CYPOR) serves
           as an electron donor in several oxygenase systems and is
           a component of nitric oxide synthases and methionine
           synthase reductases. CYPOR transfers two electrons from
           NADPH to the heme of cytochrome p450 via FAD and FMN.
           CYPOR has a C-terminal ferredoxin reducatase (FNR)- like
           FAD and NAD binding module, an FMN-binding domain, and
           an additional conecting domain (inserted within the FAD
           binding region) that orients the FNR and FMN binding
           domains. Ferredoxin-NADP+ (oxido)reductase is an
           FAD-containing enzyme that catalyzes the reversible
           electron transfer between NADP(H) and electron carrier
           proteins such as ferredoxin and flavodoxin. Isoforms of
           these flavoproteins (i.e. having a non-covalently bound
           FAD as a prosthetic group) are present in chloroplasts,
           mitochondria, and bacteria and participate in a wide
           variety of redox metabolic pathways. The C-terminal
           domain contains most of the NADP(H) binding residues and
           the N-terminal domain interacts non-covalently with the
           isoalloxazine rings of the flavin molecule which lies
           largely in a large gap betweed the two domains.
           Ferredoxin-NADP+ reductase first accepts one electron
           from reduced ferredoxin to form a flavin semiquinone
           intermediate. The enzyme then accepts a second electron
           to form FADH2, which then transfers two electrons and a
           proton to NADP+ to form NADPH..

>gnl|CDD|176249 cd08289, MDR_yhfp_like, Yhfp putative quinone oxidoreductases.
           yhfp putative quinone oxidoreductases (QOR). QOR
           catalyzes the conversion of a quinone  + NAD(P)H to a
           hydroquinone + NAD(P)+. Quinones are cyclic diones
           derived from aromatic compounds. Membrane bound QOR
           actin the respiratory chains of bacteria and
           mitochondria, while soluble QOR acts to protect from
           toxic quinones (e.g. DT-diaphorase) or as a soluble
           eye-lens protein in some vertebrates (e.g.
           zeta-crystalin). QOR reduces quinones through a
           semi-quinone intermediate via a NAD(P)H-dependent single
           electron transfer. QOR is a member of the medium chain
           dehydrogenase/reductase family, but lacks the
           zinc-binding sites of the prototypical alcohol
           dehydrogenases of this group.  NAD(P)(H)-dependent
           oxidoreductases are the major enzymes in the
           interconversion of alcohols and aldehydes, or ketones.
           Alcohol dehydrogenase in the liver converts ethanol and
           NAD+ to acetaldehyde and NADH, while in yeast and some
           other microorganisms ADH catalyzes the conversion
           acetaldehyde to ethanol in alcoholic fermentation.  ADH
           is a member of the medium chain alcohol dehydrogenase
           family (MDR), which has a NAD(P)(H)-binding domain in a
           Rossmann fold of a beta-alpha form.  The NAD(H)-binding
           region is comprised of 2 structurally similar halves,
           each of which contacts a mononucleotide.  A GxGxxG motif
           after the first mononucleotide contact half allows the
           close contact of the coenzyme with the ADH backbone.
           The N-terminal catalytic domain has a distant homology
           to GroES.  These proteins typically form dimers
           (typically higher plants, mammals) or tetramers (yeast,
           bacteria), and have 2 tightly bound zinc atoms per
           subunit, a catalytic zinc at the active site, and a
           structural zinc in a lobe of the catalytic domain.
           NAD(H) binding occurs in the cleft between the catalytic
           and coenzyme-binding domains at the active site, and
           coenzyme binding induces a conformational closing of
           this cleft. Coenzyme binding typically precedes and
           contributes to substrate binding. In human ADH
           catalysis, the zinc ion helps coordinate the alcohol,
           followed by deprotonation of a histidine, the ribose of
           NAD, a serine, then the alcohol, which allows the
           transfer of a hydride to NAD+, creating NADH and a
           zinc-bound aldehyde or ketone. In yeast and some
           bacteria, the active site zinc binds an aldehyde,
           polarizing it, and leading to the reverse reaction.
