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.
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.

sulfite reductase (SiR) multimerize with beta subunits
to catalyze the NADPH dependent reduction of sulfite to
sulfide. Beta subunits have an Fe4S4 cluster and a
siroheme, while the alpha subunits (cysJ gene) are of
the cytochrome p450 (CyPor) family having FAD and FMN as
prosthetic groups and utilizing NADPH. Cypor (including
cyt -450 reductase, nitric oxide synthase, and
methionine synthase reductase) are ferredoxin reductase
(FNR)-like proteins with an additional N-terminal FMN
domain and a connecting sub-domain inserted within the
flavin binding portion of the FNR-like domain. The
connecting domain orients the N-terminal FMN domain with
the C-terminal FNR domain.

>gnl|CDD|99800 cd06203, methionine_synthase_red, Human methionine synthase
reductase (MSR) restores methionine sythase which is
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|99799 cd06202, Nitric_oxide_synthase, The ferredoxin-reductase (FNR) like
C-terminal domain of the nitric oxide synthase (NOS)
fuses with a heme-containing N-terminal oxidase domain.
The reductase portion is similar in structure to NADPH
dependent cytochrome-450 reductase (CYPOR), having an
inserted connecting sub-domain within the FAD binding
portion of FNR. NOS differs from CYPOR in a requirement
for the cofactor tetrahydrobiopterin and unlike most
CYPOR is dimeric. Nitric oxide synthase produces nitric
oxide in the conversion of L-arginine to L-citruline.
NOS has been implicated in a variety of processes

>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).

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.

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.

of ferredoxin reductase like phenylacetic acid (PA)
degradation oxidoreductase. PA oxidoreductases of E.
coli hydroxylate PA-CoA in the second step of PA
degradation. Members of this group typically fuse a
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
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.

to utilize a variety of electron acceptors and donors
and has a variety of physiological functions including

ferredoxin reductase (FNR) proteins combine the FAD and
NAD(P) binding regions of FNR with an N-terminal
Iron-Sulfur binding cluster domain. 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|99794 cd06197, FNR_like_2, FAD/NAD(P) binding domain of ferredoxin
reductase-like proteins. Ferredoxin reductase (FNR) 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 have a variety of
physiological functions in a variety of organisms
including nitrogen assimilation, dinitrogen fixation,
steroid hydroxylation, fatty acid metabolism, oxygenase
activity, and methane assimilation. FNR has an
NAD(P)-binding sub-domain of the alpha/beta class and a
discrete (usually N-terminal) flavin sub-domain which
varies 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 two electron carriers. FNR has a strong
preference for NADP(H) vs NAD(H).
