The 20S proteasome, multisubunit proteolytic complex, is
the central enzyme of nonlysosomal protein degradation
in both the cytosol and nucleus. It is composed of 28
subunits arranged as four homoheptameric rings that
stack on top of one another forming an elongated
alpha-beta-beta-alpha cylinder with a central cavity.
The proteasome alpha and beta subunits are members of
the N-terminal nucleophile (Ntn)-hydrolase superfamily.
Their N-terminal threonine residues are exposed as a
nucleophile in peptide bond hydrolysis.Mammals have 7
alpha and 7 beta proteasome subunits while archaea have
one of each.

>gnl|CDD|238887 cd01906, proteasome_protease_HslV, proteasome_protease_HslV. This
group contains the eukaryotic proteosome alpha and beta
subunits and the prokaryotic protease hslV subunit.
Proteasomes are large multimeric self-compartmentalizing
proteases, involved in the clearance of misfolded
proteins, the breakdown of regulatory proteins, and the
processing of proteins such as the preparation of
peptides for immune presentation. Two main proteasomal
types are distinguished by their different tertiary
structures: the eukaryotic/archeal 20S proteasome and
the prokaryotic proteasome-like heat shock protein
encoded by heat shock locus V, hslV. The proteasome
core particle is a highly conserved cylindrical
structure made up of non-identical subunits that have
their active sites on the inner walls of a large central
cavity. The proteasome subunits of bacteria, archaea,
and eukaryotes all share a conserved Ntn (N terminal
nucleophile) hydrolase fold and a catalytic mechanism
involving an N-terminal nucleophilic threonine that is
exposed by post-translational processing of an inactive
propeptide.

>gnl|CDD|215805 pfam00227, Proteasome, Proteasome subunit. The proteasome is a
multisubunit structure that degrades proteins. Protein
degradation is an essential component of regulation
because proteins can become misfolded, damaged, or
unnecessary. Proteasomes and their homologues vary
greatly in complexity: from HslV (heat shock locus v),
which is encoded by 1 gene in bacteria, to the
eukaryotic 20S proteasome, which is encoded by more than
14 genes. Recently evidence of two novel groups of
bacterial proteasomes was proposed. The first is Anbu,
which is sparsely distributed among cyanobacteria and
proteobacteria. The second is call beta-proteobacteria
proteasome homologue (BPH).

>gnl|CDD|238884 cd01901, Ntn_hydrolase, The Ntn hydrolases (N-terminal nucleophile)
are a diverse superfamily of of enzymes that are
activated autocatalytically via an N-terminally lcated
nucleophilic amino acid. N-terminal nucleophile (NTN-)
hydrolase superfamily, which contains a four-layered
alpha, beta, beta, alpha core structure. This family of
hydrolases includes penicillin acylase, the 20S
proteasome alpha and beta subunits, and glutamate
synthase. The mechanism of activation of these proteins
is conserved, although they differ in their substrate
specificities. All known members catalyze the hydrolysis
of amide bonds in either proteins or small molecules,
and each one of them is synthesized as a preprotein. For
each, an autocatalytic endoproteolytic process generates
a new N-terminal residue. This mature N-terminal residue
is central to catalysis and acts as both a polarizing
base and a nucleophile during the reaction. The
N-terminal amino group acts as the proton acceptor and
activates either the nucleophilic hydroxyl in a Ser or
Thr residue or the nucleophilic thiol in a Cys residue.
The position of the N-terminal nucleophile in the active
site and the mechanism of catalysis are conserved in
this family, despite considerable variation in the
protein sequences.

Protein Tyrosine Kinases, Janus kinases. Protein
Tyrosine Kinase (PTK) family; Janus kinase (Jak)
subfamily; pseudokinase domain (repeat1). The Jak
subfamily is composed of Jak1, Jak2, Jak3, TYK2, and
similar proteins. The PTKc (catalytic domain) family to
which this subfamily belongs, is part of a larger
superfamily that includes the catalytic domains of other
kinases such as protein serine/threonine kinases, RIO
kinases, and phosphoinositide 3-kinase (PI3K). PTKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
Jak subfamily proteins are cytoplasmic (or nonreceptor)
tyr kinases containing an N-terminal FERM domain,
followed by a Src homology 2 (SH2) domain, a
pseudokinase domain, and a C-terminal catalytic tyr
kinase domain. The pseudokinase domain shows similarity
to tyr kinases but lacks crucial residues for catalytic
activity and ATP binding. It modulates the kinase
activity of the C-terminal catalytic domain. Most Jaks
are expressed in a wide variety of tissues, except for
Jak3, which is expressed only in hematopoietic cells.
Jaks are crucial for cytokine receptor signaling. They
are activated by autophosphorylation upon
cytokine-induced receptor aggregation, and subsequently
trigger downstream signaling events such as the
phosphorylation of signal transducers and activators of
transcription (STATs). Jaks are also involved in
regulating the surface expression of some cytokine
receptors. The Jak-STAT pathway is involved in many
biological processes including hematopoiesis,
immunoregulation, host defense, fertility, lactation,
growth, and embryogenesis.

>gnl|CDD|213203 cd03236, ABC_RNaseL_inhibitor_domain1, The ATP-binding cassette
domain 1 of RNase L inhibitor. The ABC ATPase, RNase L
inhibitor (RLI), is a key enzyme in ribosomal
biogenesis, formation of translation preinitiation
complexes, and assembly of HIV capsids. RLI s are not
transport proteins and thus cluster with a group of
soluble proteins that lack the transmembrane components
commonly found in other members of the family.
Structurally, RLIs have an N-terminal Fe-S domain and
two nucleotide binding domains which are arranged to
form two composite active sites in their interface
cleft. RLI is one of the most conserved enzymes between
archaea and eukaryotes with a sequence identity more
than 48%. The high degree of evolutionary conservation
suggests that RLI performs a central role in archaeal
and eukaryotic physiology.
