>gnl|CDD|119351 cd02872, GH18_chitolectin_chitotriosidase, This conserved domain
family includes a large number of catalytically inactive
chitinase-like lectins (chitolectins) including YKL-39,
YKL-40 (HCGP39), YM1, oviductin, and AMCase (acidic
mammalian chitinase), as well as catalytically active
chitotriosidases. The conserved domain is an
eight-stranded alpha/beta barrel fold belonging to the
family 18 glycosyl hydrolases. The fold has a
pronounced active-site cleft at the C-terminal end of
the beta-barrel. The chitolectins lack a key active
site glutamate (the proton donor required for hydrolytic
activity) but retain highly conserved residues involved
in oligosaccharide binding. Chitotriosidase is a
chitinolytic enzyme expressed in maturing macrophages,
which suggests that it plays a part in antimicrobial
defense. Chitotriosidase hydrolyzes chitotriose, as
well as colloidal chitin to yield chitobiose and is
therefore considered an exochitinase. Chitotriosidase
occurs in two major forms, the large form being
converted to the small form by either RNA or
post-translational processing. Although the small form,
containing the chitinase domain alone, is sufficient for
the chitinolytic activity, the additional C-terminal
chitin-binding domain of the large form plays a role in
processing colloidal chitin. The chitotriosidase gene is
nonessential in humans, as about 35% of the population
are heterozygous and 6% homozygous for an inactivated
form of the gene. HCGP39 is a 39-kDa human cartilage
glycoprotein thought to play a role in connective tissue
remodeling and defense against pathogens.

>gnl|CDD|119352 cd02873, GH18_IDGF, The IDGF's (imaginal disc growth factors) are a
family of growth factors identified in insects that
include at least five members, some of which are encoded
by genes in a tight cluster. The IDGF's have an
eight-stranded alpha/beta barrel fold and are related to
the glycosyl hydrolase family 18 (GH18) chitinases, but
they have an amino acid substitution known to abolish
chitinase catalytic activity. IDGFs may have evolved
from chitinases to gain new functions as growth factors,
interacting with cell surface glycoproteins involved in
growth-promoting processes.

type II chitinases hydrolyze chitin, an abundant polymer
of N-acetylglucosamine and have been identified in
bacteria, fungi, insects, plants, viruses, and protozoan
parasites. The structure of this domain is an
eight-stranded alpha/beta barrel with a pronounced
active-site cleft at the C-terminal end of the
beta-barrel.

>gnl|CDD|119358 cd02879, GH18_plant_chitinase_class_V, The class V plant chitinases
have a glycosyl hydrolase family 18 (GH18) domain, but
lack the chitin-binding domain present in other GH18
enzymes. The GH18 domain of the class V chitinases has
endochitinase activity in some cases and no catalytic
activity in others. Included in this family is a lectin
found in black locust (Robinia pseudoacacia) bark, which
binds chitin but lacks chitinase activity. Also
included is a chitinase-related receptor-like kinase
(CHRK1) from tobacco (Nicotiana tabacum), with an
N-terminal GH18 domain and a C-terminal kinase domain,
which is thought to be part of a plant signaling
pathway. The GH18 domain of CHRK1 is expressed
extracellularly where it binds chitin but lacks
chitinase activity.

>gnl|CDD|119357 cd02878, GH18_zymocin_alpha, Zymocin, alpha subunit. Zymocin is a
heterotrimeric enzyme that inhibits yeast cell cycle
progression. The zymocin alpha subunit has a chitinase
activity that is essential for holoenzyme action from
the cell exterior while the gamma subunit contains the
intracellular toxin responsible for G1 phase cell cycle
arrest. The zymocin alpha and beta subunits are thought
to act from the cell's exterior by docking to the cell
wall-associated chitin, thus mediating gamma-toxin
translocation. The alpha subunit has an eight-stranded
TIM barrel fold similar to that of family 18 glycosyl
hydrolases such as hevamine, chitolectin, and
chitobiase.

>gnl|CDD|119354 cd02875, GH18_chitobiase, Chitobiase (also known as
di-N-acetylchitobiase) is a lysosomal glycosidase that
hydrolyzes the reducing-end N-acetylglucosamine from the
chitobiose core of oligosaccharides during the ordered
degradation of asparagine-linked glycoproteins in
eukaryotes. Chitobiase can only do so if the asparagine
that joins the oligosaccharide to protein is previously
removed by a glycosylasparaginase. Chitobiase is
therefore the final step in the lysosomal degradation of
the protein/carbohydrate linkage component of
asparagine-linked glycoproteins. The catalytic domain of
chitobiase is an eight-stranded alpha/beta barrel fold
similar to that of other family 18 glycosyl hydrolases
such as hevamine and chitotriosidase.

>gnl|CDD|119353 cd02874, GH18_CFLE_spore_hydrolase, Cortical fragment-lytic enzyme
(CFLE) is a peptidoglycan hydrolase involved in
bacterial endospore germination. CFLE is expressed as
an inactive preprotein (called SleB) in the forespore
compartment of sporulating cells. SleB translocates
across the forespore inner membrane and is deposited as
a mature enzyme in the cortex layer of the spore. As
part of a sensory mechanism capable of initiating
germination, CFLE degrades a spore-specific
peptidoglycan constituent called muramic-acid
delta-lactam that comprises the outer cortex. CFLE has
a C-terminal glycosyl hydrolase family 18 (GH18)
catalytic domain as well as two N-terminal LysM
peptidoglycan-binding domains. In addition to SleB,
this family includes YaaH, YdhD, and YvbX from Bacillus
subtilis.
