>gnl|CDD|176117 cd08426, PBP2_LTTR_like_5, The C-terminal substrate binding domain
of an uncharacterized LysR-type transcriptional
regulator, contains the type 2 periplasmic binding fold.
LysR-transcriptional regulators comprise the largest
family of prokaryotic transcription factor. Homologs of
some of LTTRs with similar domain organizations are also
found in the archaea and eukaryotic organisms. The LTTRs
are composed of two functional domains joined by a
linker helix involved in oligomerization: an N-terminal
HTH (helix-turn-helix) domain, which is responsible for
the DNA-binding specificity, and a C-terminal
substrate-binding domain, which is structurally
homologous to the type 2 periplasmic binding proteins.
As also observed in the periplasmic binding proteins,
the C-terminal domain of the bacterial transcriptional
repressor undergoes a conformational change upon
substrate binding which in turn changes the DNA binding
affinity of the repressor. The genes controlled by the
LTTRs have diverse functional roles including amino acid
biosynthesis, CO2 fixation, antibiotic resistance,
degradation of aromatic compounds, nodule formation of
nitrogen-fixing bacteria, and synthesis of virulence
factors, to a name a few. This substrate-binding domain
shows significant homology to the type 2 periplasmic
binding proteins (PBP2), which are responsible for the
uptake of a variety of substrates such as phosphate,
sulfate, polysaccharides, lysine/arginine/ornithine, and
histidine. The PBP2 bind their ligand in the cleft
between these domains in a manner resembling a Venus
flytrap. After binding their specific ligand with high
affinity, they can interact with a cognate membrane
transport complex comprised of two integral membrane
domains and two cytoplasmically located ATPase domains.
This interaction triggers the ligand translocation
across the cytoplasmic membrane energized by ATP
hydrolysis.

>gnl|CDD|213289 cd05922, FACL_like_6, Uncharacterized subfamily of fatty acid CoA
ligase (FACL). Fatty acyl-CoA ligases catalyze the
ATP-dependent activation of fatty acids in a two-step
reaction. The carboxylate substrate first reacts with
ATP to form an acyl-adenylate intermediate, which then
reacts with CoA to produce an acyl-CoA ester. This is a
required step before free fatty acids can participate in
most catabolic and anabolic reactions.

>gnl|CDD|128341 smart00026, EPEND, Ependymins. Ependymins are the predominant
proteins in the cerebrospinal fluid (CSF) of teleost
fish. They have been implicated in the neurochemistry of
memory and neuronal regeneration. They are glycoproteins
of about 200 amino acids that can bind calcium. Four
cysteines are conserved that probably form disulfide
bonds.
