C-terminal ACT domain of the bifunctional chorismate
mutase-prephenate dehydratase (CM-PDT) enzyme and the

P-protein (CM-PDT) has three domains with an N-terminal
domain with chorismate mutase activity, a middle domain
with prephenate dehydratase activity, and an ACT
regulatory C-terminal domain. The prephenate dehydratase
enzyme has a PDT and ACT domain. The ACT domain is
essential to bring about the negative allosteric
regulation by L-Phe binding. L-Phe binds with positive
cooperativity; with this binding, there is a shift in
the protein to less active tetrameric and higher
oligomeric forms from a more active dimeric form.

amino acid hydroxylases (AAAH): Phenylalanine
hydroxylases (PAH), tyrosine hydroxylases (TH) and
tryptophan hydroxylases (TPH), both peripheral (TPH1)

oligomeric state of the enzyme forming a domain-swapped
tetrameric coiled-coil. The PAH, TH, and TPH enzymes
contain highly conserved catalytic domains but distinct
N-terminal ACT domains and differ in their mechanisms of

form. This model describes the larger, tetrameric form
of phenylalanine-4-hydroxylase, as found in metazoans.
The enzyme irreversibly converts phenylalanine to
tryosine and is known to be the rate-limiting step in
phenylalanine catabolism in some systems. It is closely
related to metazoan tyrosine 3-monooxygenase and
tryptophan 5-monoxygenase, and more distantly to
monomeric phenylalanine-4-hydroxylases of some
Gram-negative bacteria. The member of this family from
Drosophila has been described as having both
phenylalanine-4-hydroxylase and tryptophan
5-monoxygenase activity (PMID:1371286). However, a
Drosophila member of the tryptophan 5-monoxygenase clade
has subsequently been discovered.

(PAH). ACT domain of the nonheme iron-dependent
aromatic amino acid hydroxylase, phenylalanine
hydroxylases (PAH). PAH catalyzes the hydroxylation of
L-Phe to L-Tyr, the first step in the catabolic
degradation of L-Phe. In PAH, an autoregulatory
sequence, N-terminal of the ACT domain, extends across
the catalytic domain active site and regulates the
enzyme by intrasteric regulation. It appears that the
activation by L-Phe induces a conformational change that
converts the enzyme to a high-affinity and high-activity
state. Modulation of activity is achieved through
inhibition by BH4 and activation by phosphorylation of
serine residues of the autoregulatory region. The
molecular basis for the cooperative activation process
is not fully understood yet. Members of this CD belong
to the superfamily of ACT regulatory domains.

>gnl|CDD|153139 cd02116, ACT, ACT domains are commonly involved in specifically
binding an amino acid or other small ligand leading to
regulation of the enzyme. Members of this CD belong to
the superfamily of ACT regulatory domains. Pairs of ACT
domains are commonly involved in specifically binding an
amino acid or other small ligand leading to regulation
of the enzyme. The ACT domain has been detected in a
number of diverse proteins; some of these proteins are
involved in amino acid and purine biosynthesis,
phenylalanine hydroxylation, regulation of bacterial
metabolism and transcription, and many remain to be
characterized. ACT domain-containing enzymes involved in
amino acid and purine synthesis are in many cases
allosteric enzymes with complex regulation enforced by
the binding of ligands. The ACT domain is commonly
involved in the binding of a small regulatory molecule,
such as the amino acids L-Ser and L-Phe in the case of
D-3-phosphoglycerate dehydrogenase and the bifunctional
chorismate mutase-prephenate dehydratase enzyme
(P-protein), respectively. Aspartokinases typically
consist of two C-terminal ACT domains in a tandem
repeat, but the second ACT domain is inserted within
the first, resulting in, what is normally the terminal
beta strand of ACT2, formed from a region N-terminal of
ACT1. ACT domain repeats have been shown to have
nonequivalent ligand-binding sites with complex
regulatory patterns such as those seen in the
bifunctional enzyme, aspartokinase-homoserine
dehydrogenase (ThrA). In other enzymes, such as
phenylalanine hydroxylases, the ACT domain appears to
function as a flexible small module providing allosteric
regulation via transmission of conformational changes,
these conformational changes are not necessarily
initiated by regulatory ligand binding at the ACT domain
itself. ACT domains are present either singularly, N- or
C-terminal, or in pairs present C-terminal or between
two catalytic domains. Unique to cyanobacteria are four
ACT domains C-terminal to an aspartokinase domain. A few
proteins are composed almost entirely of ACT domain
repeats as seen in the four ACT domain protein, the ACR
protein, found in higher plants; and the two ACT domain
protein, the glycine cleavage system transcriptional
repressor (GcvR) protein, found in some bacteria. Also

Streptococcus pneumoniae ACT domain protein

>gnl|CDD|190133 pfam01842, ACT, ACT domain. This family of domains generally have
a regulatory role. ACT domains are linked to a wide
range of metabolic enzymes that are regulated by amino
acid concentration. Pairs of ACT domains bind
specifically to a particular amino acid leading to
regulation of the linked enzyme. The ACT domain is found
in: D-3-phosphoglycerate dehydrogenase EC:1.1.1.95,
which is inhibited by serine. Aspartokinase EC:2.7.2.4,
which is regulated by lysine. Acetolactate synthase
small regulatory subunit, which is inhibited by valine.
Phenylalanine-4-hydroxylase EC:1.14.16.1, which is
regulated by phenylalanine. Prephenate dehydrogenase
EC:4.2.1.51. formyltetrahydrofolate deformylase
EC:3.5.1.10, which is activated by methionine and
inhibited by glycine. GTP pyrophosphokinase EC:2.7.6.5.

This model describes tryptophan 5-monooxygenase, a
member of the family of tetrameric, biopterin-dependent
aromatic amino acid hydroxylases found in metazoans. It
is closely related to tetrameric
phenylalanine-4-hydroxylase and tyrosine
3-monooxygenase, and more distantly related to the
monomeric phenylalanine-4-hydroxylase found in some
Gram-negative bacteria [Energy metabolism, Amino acids

>gnl|CDD|241031 cd12587, RRM1_PSF, RNA recognition motif 1 in vertebrate
polypyrimidine tract-binding protein
(PTB)-associated-splicing factor (PSF). This subgroup
corresponds to the RRM1 of PSF, also termed proline- and
glutamine-rich splicing factor, or 100 kDa DNA-pairing
protein (POMp100), or 100 kDa subunit of DNA-binding
p52/p100 complex, a multifunctional protein that
mediates diverse activities in the cell. It is
ubiquitously expressed and highly conserved in
vertebrates. PSF binds not only RNA but also both
single-stranded DNA (ssDNA) and double-stranded DNA
(dsDNA) and facilitates the renaturation of
complementary ssDNAs. Besides, it promotes the formation
of D-loops in superhelical duplex DNA, and is involved
in cell proliferation. PSF can also interact with
multiple factors. It is an RNA-binding component of
spliceosomes and binds to insulin-like growth factor
response element (IGFRE). PSF functions as a
transcriptional repressor interacting with Sin3A and
mediating silencing through the recruitment of histone
deacetylases (HDACs) to the DNA binding domain (DBD) of
nuclear hormone receptors. Additionally, PSF is an
essential pre-mRNA splicing factor and is dissociated
from PTB and binds to U1-70K and serine-arginine (SR)
proteins during apoptosis. PSF forms a heterodimer with
the nuclear protein p54nrb, also known as non-POU
domain-containing octamer-binding protein (NonO). The
PSF/p54nrb complex displays a variety of functions, such
as DNA recombination and RNA synthesis, processing, and
transport. PSF contains two conserved RNA recognition
motifs (RRMs), also termed RBDs (RNA binding domains) or
RNPs (ribonucleoprotein domains), which are responsible
for interactions with RNA and for the localization of
the protein in speckles. It also contains an N-terminal
region rich in proline, glycine, and glutamine residues,
which may play a role in interactions recruiting other
molecules. .

debranching enzyme possesses two different catalytic
activities; oligo-1,4-->1,4-glucantransferase (EC
2.4.1.25) and amylo-1,6-glucosidase (EC 3.2.1.33). Site
directed mutagenesis studies in S. cerevisiae indicate
that the transferase and glucosidase activities are
independent and located in different regions of the
polypeptide chain. Proteins in this model belong to the
larger alpha-amylase family. The model covers eukaryotic
proteins with a seed composed of human, nematode and
yeast sequences. Yeast seed sequence is well
characterized. The model is quite rigorous; either query
sequence yields large bit score or it fails to hit the
model altogether. There doesn't appear to be any middle
ground [Energy metabolism, Biosynthesis and degradation
of polysaccharides].
