>gnl|CDD|143398 cd07079, ALDH_F18-19_ProA-GPR, Gamma-glutamyl phosphate reductase
(GPR), aldehyde dehydrogenase families 18 and 19.
Gamma-glutamyl phosphate reductase (GPR), a L-proline
biosynthetic pathway (PBP) enzyme that catalyzes the
NADPH dependent reduction of L-gamma-glutamyl
5-phosphate into L-glutamate 5-semialdehyde and
phosphate. The glutamate route of the PBP involves two
enzymatic steps catalyzed by gamma-glutamyl kinase (GK,
EC 2.7.2.11) and GPR (EC 1.2.1.41). These enzymes are
fused into the bifunctional enzyme, ProA or
delta(1)-pyrroline-5-carboxylate synthetase (P5CS) in
plants and animals, whereas they are separate enzymes in
bacteria and yeast. In humans, the P5CS (ALDH18A1), an
inner mitochondrial membrane enzyme, is essential to the
de novo synthesis of the amino acids proline and
arginine. Tomato (Lycopersicon esculentum) has both the
prokaryotic-like polycistronic operons encoding GK and
GPR (PRO1, ALDH19) and the full-length, bifunctional
P5CS (PRO2, ALDH18B1).

>gnl|CDD|143395 cd06534, ALDH-SF, NAD(P)+-dependent aldehyde dehydrogenase
superfamily. The aldehyde dehydrogenase superfamily
(ALDH-SF) of NAD(P)+-dependent enzymes, in general,
oxidize a wide range of endogenous and exogenous
aliphatic and aromatic aldehydes to their corresponding
carboxylic acids and play an important role in
detoxification. Besides aldehyde detoxification, many
ALDH isozymes possess multiple additional catalytic and
non-catalytic functions such as participating in
metabolic pathways, or as binding proteins, or
osmoregulants, to mention a few. The enzyme has three
domains, a NAD(P)+ cofactor-binding domain, a catalytic
domain, and a bridging domain; and the active enzyme is
generally either homodimeric or homotetrameric. The
catalytic mechanism is proposed to involve cofactor
binding, resulting in a conformational change and
activation of an invariant catalytic cysteine
nucleophile. The cysteine and aldehyde substrate form an
oxyanion thiohemiacetal intermediate resulting in
hydride transfer to the cofactor and formation of a
thioacylenzyme intermediate. Hydrolysis of the
thioacylenzyme and release of the carboxylic acid
product occurs, and in most cases, the reduced cofactor
dissociates from the enzyme. The evolutionary
phylogenetic tree of ALDHs appears to have an initial
bifurcation between what has been characterized as the
classical aldehyde dehydrogenases, the ALDH family
(ALDH) and extended family members or aldehyde
dehydrogenase-like (ALDH-L) proteins. The ALDH proteins
are represented by enzymes which share a number of
highly conserved residues necessary for catalysis and
cofactor binding and they include such proteins as
retinal dehydrogenase, 10-formyltetrahydrofolate
dehydrogenase, non-phosphorylating glyceraldehyde
3-phosphate dehydrogenase,
delta(1)-pyrroline-5-carboxylate dehydrogenases,
alpha-ketoglutaric semialdehyde dehydrogenase,
alpha-aminoadipic semialdehyde dehydrogenase, coniferyl
aldehyde dehydrogenase and succinate-semialdehyde
dehydrogenase. Included in this larger group are all
human, Arabidopsis, Tortula, fungal, protozoan, and
Drosophila ALDHs identified in families ALDH1 through
ALDH22 with the exception of families ALDH18, ALDH19,
and ALDH20 which are present in the ALDH-like group. The
ALDH-like group is represented by such proteins as
gamma-glutamyl phosphate reductase, LuxC-like acyl-CoA
reductase, and coenzyme A acylating aldehyde
dehydrogenase. All of these proteins have a conserved
cysteine that aligns with the catalytic cysteine of the
ALDH group.

>gnl|CDD|217142 pfam02613, Nitrate_red_del, Nitrate reductase delta subunit.
This family is the delta subunit of the nitrate
reductase enzyme, The delta subunit is not part of the
nitrate reductase enzyme but is most likely needed for
assembly of the multi-subunit enzyme complex. In the
absence of the delta subunit the core alpha beta enzyme
complex is unstable. The delta subunit is essential for
enzyme activity in vivo and in vitro. The nitrate
reductase enzyme, EC:1.7.99.4 catalyze the conversion
of nitrite to nitrate via the reduction of an acceptor.
The nitrate reductase enzyme is composed of three
subunits. Nitrate is the most widely used alternative
electron acceptor after oxygen. This family also now
contains the family TorD, a family of cytoplasmic
chaperone proteins; like many prokaryotic
molybdoenzymes, the TMAO reductase (TorA) of
Escherichia coli requires the insertion of a
bis(molybdopterin guanine dinucleotide) molybdenum
(bis(MGD)Mo) cofactor in its catalytic site to be
active and translocated to the periplasm. The TorD
chaperone increases apoTorA activation up to four-fold,
allowing maturation of most of the apoprotein.
Therefore TorD is involved in the first step of TorA
maturation to make it competent to receive the
cofactor.

Serine/Threonine Kinase, MAP/ERK kinase kinase 3.
Serine/threonine kinases (STKs), MAP/ERK kinase kinase 3
(MEKK3) subfamily, catalytic (c) domain. STKs catalyze
the transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
MEKK3 subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. MEKK3 is a mitogen-activated protein kinase
(MAPK) kinase kinase (MAPKKK or MKKK or MAP3K), that
phosphorylates and activates the MAPK kinase MEK5 (or
MKK5), which in turn phosphorylates and activates
extracellular signal-regulated kinase 5 (ERK5). The ERK5
cascade plays roles in promoting cell proliferation,
differentiation, neuronal survival, and neuroprotection.
MEKK3 plays an essential role in embryonic angiogenesis
and early heart development. In addition, MEKK3 is
involved in interleukin-1 receptor and Toll-like
receptor 4 signaling. It is also a specific regulator of
the proinflammatory cytokines IL-6 and GM-CSF in some
immune cells. MEKK3 also regulates calcineurin, which
plays a critical role in T cell activation, apoptosis,
skeletal myocyte differentiation, and cardiac
hypertrophy.
