>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.

>gnl|CDD|99811 cd06215, FNR_iron_sulfur_binding_1, Iron-sulfur binding ferredoxin
reductase (FNR) proteins combine the FAD and NAD(P)
binding regions of FNR with an 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 portion of the FAD/NAD binding domain
contains most of the NADP(H) binding residues and the
N-terminal sub-domain interacts non-covalently with the
isoalloxazine rings of the flavin molecule which lies
largely in a large gap betweed the two domains. In this
ferredoxin like sub-group, the FAD/NAD sub-domains is
typically fused to a C-terminal iron-sulfur binding
domain. Iron-sulfur proteins play an important role in
electron transfer processes and in various enzymatic
reactions. The family includes plant and algal
ferredoxins which act as electron carriers in
photosynthesis and ferredoxins which participate in
redox chains from bacteria to mammals. Ferredoxin
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.

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+

>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|107240 cd06490, p23_NCB5OR, p23_like domain found in NAD(P)H cytochrome b5
(NCB5) oxidoreductase (OR) and similar proteins. NCB5OR
is widely expressed in human organs and tissues and is
localized in the ER (endoplasmic reticulum). It appears
to play a critical role in maintaining viable pancreatic
beta cells. Mice homozygous for a targeted knockout (KO)
of the gene encoding NCB5OR develop an early-onset
nonautoimmune diabetes phenotype with a non-inflammatory
beta-cell deficiency. The role of NCB5OR in beta cells
may be in maintaining or regulating their redox status.
Proteins in this group in addition contain an N-terminal
cytochrome b5 domain and a C-terminal cytochrome b5
oxidoreductase domain. The gene encoding NCB5OR has
been considered as a positional candidate for type II
diabetes and other diabetes subtypes related to B-cell
dysfunction, however variation in its coding region does
not appear not to be a major contributor to the
pathogenesis of these diseases.

complexes and has the features of a cochaperone. Human
(h) Sgt1 interacts with both Hsp70 and Hsp90, and has
been shown to bind Hsp90 through its CS domain.
Saccharomyces cerevisiae (Sc) Sgt1 is a subunit of both
core kinetochore and SCF (Skp1-Cul1-F-box) ubiquitin
ligase complexes. Sgt1 is required for pathogen
resistance in plants. ScSgt1 is needed for the G1/S and
G2/M cell-cycle transitions, and for assembly of the
core kinetochore complex (CBF3) via activation of Ctf13,
the F-box protein. Binding of Hsp82 (a yeast Hsp90
homologue) to ScSgt1, promotes the binding of Sgt1 to
Skp1 and of Skp1 to Ctf13. Some proteins in this group
have an SGT1-specific (SGS) domain at the extreme
C-terminus. The ScSgt1-SGS domain binds adenylate
cyclase. The hSgt1-SGS domain interacts with some S100
family proteins, and studies suggest that the
interaction of hSgt1 with Hsp90 and Hsp70 may be
regulated by S100A6 in a Ca2+ dependent fashion. This
group also includes the p23_like domains of Melusin and
NAD(P)H cytochrome b5 (NCB5) oxidoreductase (OR).
Melusin is a vertebrate protein which interacts with two
splice variants of beta1 integrin, and NCB5OR plays a
part in maintaining viable pancreatic beta cells.

FAD, FMN, or riboflavin via NAD(P)H. Flavin is used as a
substrate, rather than a tightly bound prosthetic group

>gnl|CDD|99804 cd06208, CYPOR_like_FNR, These ferredoxin reductases are related to
the NADPH cytochrome p450 reductases (CYPOR), but lack
the FAD-binding region connecting sub-domain.
Ferredoxin-NADP+ reductase (FNR) 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
between 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. CYPOR serves as an electron donor in several
oxygenase systems and is a component of nitric oxide

reductases. CYPOR transfers two electrons from NADPH to
the heme of cytochrome p450 via FAD and FMN. CYPOR has
a C-terminal FNR-like FAD and NAD binding module, an
FMN-binding domain, and an additional connecting domain
(inserted within the FAD binding region) that orients
the FNR and FMN -binding domains. 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.

the only redox reaction in pyrimidine de novo
biosynthesis. They catalyze the oxidation of
(S)-dihydroorotate to orotate coupled with the reduction
of NAD+. In L. lactis, DHOD B (encoded by pyrDa) is
co-expressed with pyrK and both gene products are
required for full activity, as well as NAD binding.
NAD(P) binding domain of ferredoxin reductase-like
proteins 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 domain may contain a flavin prosthetic
group, as in flavoenzymes, or use flavin as a substrate.
Ferredoxin is reduced in the final stage of photosystem
I. The flavoprotein Ferredoxin-NADP+ reductase transfers
electrons from reduced ferredoxin to FAD, forming FADH2
via a semiquinone intermediate, and then transfers a
hydride ion to convert NADP+ to NADPH.

thioesterase. The tol-pal system consists of five
critical genes. Inner membrane proteins TolQ and TolR
convert protomotive force to energy that is transduced
through TolA to an outer membrane complex of TolB and
Pal. The system is known to be required to maintain
outer membrane integrity. In a system with several
homologous parts, ExbB and ExbD transduces energy
through TonB to a variety of outer membrane proteins,
many of which are siderophore receptors. The tol-pal
system therefore may also be involved in transport. This
family consists of a protein nearly always found in
operons with the genes of the tol-pal system. The
significance of this thioesterase to the tol-pal system
is unclear, but either of two observations may be
relevant. First, Pal, or peptidoglycan-associated
lipoprotein, has a conserved N-terminal cleavage and
acylation that makes it a lipoprotein. Second, the
tol-pal system is implicated not only in the import of
certain organics but also in the maintenance of outer
membrane integrity (by an unknown mechanism).
