alphaA-crystallin (HspB4), alphaB-crystallin (HspB5),
and the small heat shock protein (sHsp) HspB6, also
known as Hsp20. sHsps are molecular chaperones that
suppress protein aggregation and protect against cell
stress, and are generally active as large oligomers
consisting of multiple subunits. Alpha crystallin, an
abundant protein in the mammalian lens, is a large (700
kDa) heteropolymer composed of HspB4 and HspB5,
generally in a molar ratio of HspB4:HspB5 of 3:1. Only
trace amounts of HspB4 are found in tissues other than
the lens. HspB5 on the other hand is also expressed
constitutively in other tissues including brain, heart,
and type I and type IIa skeletal muscle fibers, and in
several cancers including gliomas, renal cell
carcinomas, basal-like and metaplastic breast
carcinomas, and head and neck cancer. HspB5's
functions include effects on the apoptotic pathway and
on metastasis. Phosphorylation of HspB5 reduces its
oligomerization and anti-apoptotic activities. HspB5
is protective in demyelinating disease such as multiple
sclerosis (MS), being a negative regulator of
inflammation. In early active MS lesions it is the most
abundant gene transcript and an autoantigen, the immune
response against it would disrupt its function and
worsen inflammation and demyelination. Given as therapy
for ongoing demyelinating disease it may counteract
this effect. It is an autoantigen in the pathogenesis
of various other inflammatory disorders including
Lens-associated uveitis (LAU), and Behcet's disease.
Mutations in HspB5 have been associated with diseases
including dominant cataract and desmin-related
myopathy. Mutations in HspB4 have been associated with
Autosomal Dominant Congenital Cataract (ADCC). HspB6
(Hsp20) is ubiquitous and is involved in diverse
functions including regulation of glucose transport and
contraction of smooth muscle, in platelet aggregation,
in cardioprotection, and in the prevention of
apoptosis. It interacts with the universal scaffolding
and adaptor protein 14-3-3, and also with the
proapoptotic protein Bax.

mammalian small (s)heat shock protein (Hsp)-27 (also
denoted HspB1 in human) and similar proteins. sHsps are
molecular chaperones that suppress protein aggregation
and protect against cell stress, and are generally
active as large oligomers consisting of multiple
subunits. Hsp27 shows enhanced synthesis in response to
stress. It is a molecular chaperone which interacts
with a large number of different proteins. It is found
in many types of human cells including breast, uterus,
cervix, platelets and cancer cells. Hsp27 has diverse
cellular functions including, chaperoning, regulation
of actin polymerization, keratinocyte differentiation,
regulation of inflammatory pathways in keratinocytes,
and protection from oxidative stress through modulating
glutathione levels. It is also a subunit of
AUF1-containing protein complexes. It has been linked
to several transduction pathways regulating cellular
functions including differentiation, cell growth,
development, and apoptosis. Its activity can be
regulated by phosphorylation. Its unphosphorylated
state is a high molecular weight aggregated form
(100-800kDa) composed of up to 24 subunits, which forms
as a result of multiple interactions within the ACD,
and is required for chaperone function and resistance
to oxidative stress. Upon phosphorylation these large
aggregates rapidly disassociate to smaller oligomers
and chaperone activity is modified. High constitutive
levels of Hsp27 have been detected in various cancer
cells, in particular those of carcinoma origin.
Over-expression of Hsp27 has a protective effect
against various diseases-processes, including
Huntington's disease. Mutations in Hsp27 have been
associated with a form of distal hereditary motor
neuropathy type II and Charcot-Marie-Tooth disease type
2.

mammalian small heat shock protein (sHsp) HspB2/heat
shock 27kDa protein 2 and similar proteins. sHsps are
molecular chaperones that suppress protein aggregation
and protect against cell stress, and are generally
active as large oligomers consisting of multiple
subunits. HspB2 is preferentially and constitutively
expressed in skeletal muscle and heart. HspB2 shows
homooligomeric activity and forms aggregates in muscle
cytosol. Although its expression is not induced by heat
shock, it redistributes to the insoluble fraction in
response to heat shock. In the mouse heart, HspB2 plays
a role in maintaining energetic balance, by protecting
cardiac energetics during ischemia/reperfusion, and
allowing for increased work during acute inotropic
challenge. hHspB2 [previously also known as myotonic
dystrophy protein kinase (DMPK) binding protein (MKBP)]
is selectively up-regulated in skeletal muscles from
myotonic dystrophy patients. The ACD of hHspB2 binds
the DMPK kinase domain. In vitro, hHspB2 enhances the
kinase activity of DMPK and confers thermoresistance.
The hHspB2 gene lies less than 1kb from the 5 prime end
of the related alphaB (HspB4)-crystallin gene, with the
opposite transcription direction. These two genes may
share regulatory elements for their expression.

These dimers initiate the interaction with non-native
substrate proteins and re-assemble into large globular
assemblies having one monomer of substrate bound per
dimer. This group also contains Arabidopsis thaliana
(Ath) Hsp15.7, a peroxisomal matrix protein which can
complement the morphological phenotype of S. cerevisiae
mutants deficient in Hsps26. AthHsp15.7 is minimally
expressed under normal conditions and is strongly
induced by heat and oxidative stress. Also belonging to
this group is wheat HSP16.9 which differs in quaternary
structure from the shell-type particles of ScHsp26, it
assembles as a dodecameric double disc, with each disc
organized as a trimer of dimers.

Escherichia coli inclusion body-associated proteins
IbpA and IbpB, and similar proteins. IbpA and IbpB are
16 kDa small heat shock proteins (sHsps). sHsps are
molecular chaperones that suppress protein aggregation
and protect against cell stress, and are generally
active as large oligomers consisting of multiple
subunits. IbpA and IbpB are produced during high-level
production of various heterologous proteins,
specifically human prorenin, renin and bovine
insulin-like growth factor 2 (bIGF-2), and are strongly
associated with inclusion bodies containing these
heterologous proteins. IbpA and IbpB work as an
integrated system to stabilize thermally aggregated
proteins in a disaggregation competent state. The
chaperone activity of IbpB is also significantly
elevated as the temperature increases from normal to
heat shock. The high temperature results in the
disassociation of 2-3-MDa IbpB oligomers into smaller
approximately 600-kDa structures. This elevated
activity seen under heat shock conditions is retained
for an extended period of time after the temperature is
returned to normal. IbpA also forms multimers.

>gnl|CDD|99867 cd06114, EcCS_like, Escherichia coli (Ec) citrate synthase (CS)
GltA_like. CS catalyzes the condensation of acetyl
coenzyme A (AcCoA) and oxalacetate (OAA) to form citrate
and coenzyme A (CoA), the first step in the citric acid
cycle (TCA or Krebs cycle). The overall CS reaction is
thought to proceed through three partial reactions and
involves both closed and open conformational forms of
the enzyme: a) the carbanion or equivalent is generated
from AcCoA by base abstraction of a proton, b) the
nucleophilic attack of this carbanion on OAA to generate
citryl-CoA, and c) the hydrolysis of citryl-CoA to
produce citrate and CoA. There are two types of CSs:
type I CS and type II CSs. Type I CSs are found in
eukarya, gram-positive bacteria, archaea, and in some
gram-negative bacteria and are homodimers with both
subunits participating in the active site. Type II CSs
are unique to gram-negative bacteria and are
homohexamers of identical subunits (approximated as a
trimer of dimers). Some type II CSs including EcCS are
strongly and specifically inhibited by NADH through an
allosteric mechanism. Included in this group is an
NADH-insensitive type II Acetobacter acetii CS which has
retained many of the residues used by EcCS for NADH
binding.

(CS)-II_like. CS catalyzes the condensation of acetyl
coenzyme A (AcCoA) and oxalacetate (OAA) to form citrate
and coenzyme A (CoA), the first step in the citric acid
cycle (TCA or Krebs cycle). 2MCS catalyzes the
condensation of propionyl-coenzyme A (PrCoA) and OAA to
form 2-methylcitrate and CoA during propionate
metabolism. The overall CS reaction is thought to
proceed through three partial reactions: a) the
carbanion or equivalent is generated from AcCoA by base
abstraction of a proton, b) the nucleophilic attack of
this carbanion on OAA to generate citryl-CoA, and c) the
hydrolysis of citryl-CoA to produce citrate and CoA.
This group contains proteins similar to BsCS-II, the
major CS of the gram-positive bacterium Bacillus
subtilis. A mutation in the gene which encodes BsCS-II
(citZ gene) has been described which resulted in a
significant loss of CS activity, partial glutamate
auxotrophy, and a sporulation deficiency, all of which
are characteristic of strains defective in the Krebs
cycle. Streptococcus mutans CS, found in this group, may
participate in a pathway for the anaerobic biosynthesis
of glutamate. This group also contains functionally
uncharacterized CSs of various gram-negative bacteria.
Some of the gram-negative species represented in this
group have a second CS isozyme found in another group.
This group contains proteins which functions exclusively
as either a CS or a 2MCS, as well as those with relaxed
specificity which have dual functions as both a CS and a
2MCS.
