>gnl|CDD|132999 cd00899, b4GalT, Beta-4-Galactosyltransferase is involved in the
formation of the poly-N-acetyllactosamine core
structures present in glycoproteins and
glycosphingolipids. Beta-4-Galactosyltransferase
transfers galactose from uridine diphosphogalactose to
the terminal beta-N-acetylglucosamine residues, hereby
forming the poly-N-acetyllactosamine core structures
present in glycoproteins and glycosphingolipids. At
least seven homologous beta-4-galactosyltransferase
isoforms have been identified that use different types
of glycoproteins and glycolipids as substrates. Of the
seven identified members of the
beta-1,4-galactosyltransferase subfamily (beta1,4-Gal-T1
to -T7), b1,4-Gal-T1 is most characterized
(biochemically). It is a Golgi-resident type II membrane
enzyme with a cytoplasmic domain, membrane spanning
region, and a stem region and catalytic domain facing
the lumen.

of unknown function. GT-2 includes diverse families of
glycosyltransferases with a common GT-A type structural
fold, which has two tightly associated beta/alpha/beta
domains that tend to form a continuous central sheet of
at least eight beta-strands. These are enzymes that
catalyze the transfer of sugar moieties from activated
donor molecules to specific acceptor molecules, forming
glycosidic bonds. Glycosyltransferases have been
classified into more than 90 distinct sequence based
families.

>gnl|CDD|133042 cd06420, GT2_Chondriotin_Pol_N, N-terminal domain of Chondroitin
polymerase functions as a GalNAc transferase.
Chondroitin polymerase is a two domain, bi-functional
protein. The N-terminal domain functions as a GalNAc
transferase. The bacterial chondroitin polymerase
catalyzes elongation of the chondroitin chain by
alternatively transferring the GlcUA and GalNAc moiety
from UDP-GlcUA and UDP-GalNAc to the non-reducing ends
of the chondroitin chain. The enzyme consists of
N-terminal and C-terminal domains in which the two
active sites catalyze the addition of GalNAc and GlcUA,
respectively. Chondroitin chains range from 40 to over
100 repeating units of the disaccharide. Sulfated
chondroitins are involved in the regulation of various
biological functions such as central nervous system
development, wound repair, infection, growth factor
signaling, and morphogenesis, in addition to its
conventional structural roles. In Caenorhabditis
elegans, chondroitin is an essential factor for the worm
to undergo cytokinesis and cell division. Chondroitin is
synthesized as proteoglycans, sulfated and secreted to
the cell surface or extracellular matrix.

>gnl|CDD|132997 cd00761, Glyco_tranf_GTA_type, Glycosyltransferase family A (GT-A)
includes diverse families of glycosyl transferases with
a common GT-A type structural fold.
Glycosyltransferases (GTs) are enzymes that synthesize
oligosaccharides, polysaccharides, and glycoconjugates
by transferring the sugar moiety from an activated
nucleotide-sugar donor to an acceptor molecule, which
may be a growing oligosaccharide, a lipid, or a protein.
Based on the stereochemistry of the donor and acceptor
molecules, GTs are classified as either retaining or
inverting enzymes. To date, all GT structures adopt one
of two possible folds, termed GT-A fold and GT-B fold.
This hierarchy includes diverse families of glycosyl
transferases with a common GT-A type structural fold,
which has two tightly associated beta/alpha/beta domains
that tend to form a continuous central sheet of at least
eight beta-strands. The majority of the proteins in this
superfamily are Glycosyltransferase family 2 (GT-2)
proteins. But it also includes families GT-43, GT-6,
GT-8, GT13 and GT-7; which are evolutionarily related to
GT-2 and share structure similarities.

>gnl|CDD|133004 cd02510, pp-GalNAc-T, pp-GalNAc-T initiates the formation of
mucin-type O-linked glycans. UDP-GalNAc: polypeptide
alpha-N-acetylgalactosaminyltransferases (pp-GalNAc-T)
initiate the formation of mucin-type, O-linked glycans
by catalyzing the transfer of
alpha-N-acetylgalactosamine (GalNAc) from UDP-GalNAc to
hydroxyl groups of Ser or Thr residues of core proteins
to form the Tn antigen (GalNAc-a-1-O-Ser/Thr). These
enzymes are type II membrane proteins with a GT-A type
catalytic domain and a lectin domain located on the
lumen side of the Golgi apparatus. In human, there are
15 isozymes of pp-GalNAc-Ts, representing the largest of
all glycosyltransferase families. Each isozyme has
unique but partially redundant substrate specificity for
glycosylation sites on acceptor proteins.
