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

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.

a component of nitric oxide synthases and methionine

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

>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|99789 cd06192, DHOD_e_trans_like, FAD/NAD binding domain (electron
transfer subunit) of dihydroorotate dehydrogenase-like
proteins. Dihydroorotate dehydrogenases (DHODs) catalyze
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) which then transfers a
hydride ion to convert NADP+ to NADPH.
