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.

A4GalT_like proteins catalyze the addition of galactose or glucose residues to the lipooligosaccharide (LOS) or lipopolysaccharide (LPS) of the bacterial cell surface; The members of this family of glycosyltransferases catalyze the addition of galactose or glucose residues to the lipooligosaccharide (LOS) or lipopolysaccharide (LPS) of the bacterial cell surface. The enzymes exhibit broad substrate specificities. The known functions found in this family include: Alpha-1,4-galactosyltransferase, LOS-alpha-1,3-D-galactosyltransferase, UDP-glucose:(galactosyl) LPS alpha1,2-glucosyltransferase, UDP-galactose: (glucosyl) LPS alpha1,2-galactosyltransferase, and UDP-glucose:(glucosyl) LPS alpha1,2-glucosyltransferase. Alpha-1,4-galactosyltransferase from N. meningitidis adds an alpha-galactose from UDP-Gal (the donor) to a terminal lactose (the acceptor) of the LOS structure of outer membrane. LOSs are virulence factors that enable the organism to evade the immune system of host cells. In E. coli, the three alpha-1,2-glycosyltransferases, that are involved in the synthesis of the outer core region of the LPS, are all members of this family. The three enzymes share 40 % of sequence identity, but have different sugar donor or acceptor specificities, representing the structural diversity of LPS.

LARGE catalytic domain has closest homology to GT8 glycosyltransferase involved in lipooligosaccharide synthesis; The catalytic domain of LARGE is a putative glycosyltransferase. Mutations of LARGE in mouse and human cause dystroglycanopathies, a disease associated with hypoglycosylation of the membrane protein alpha-dystroglycan (alpha-DG) and consequent loss of extracellular ligand binding. LARGE needs to both physically interact with alpha-dystroglycan and function as a glycosyltransferase in order to stimulate alpha-dystroglycan hyperglycosylation. LARGE localizes to the Golgi apparatus and contains three conserved DxD motifs. While two of the motifs are indispensible for glycosylation function, one is important for localization of th eenzyme. LARGE was originally named because it covers approximately large trunck of genomic DNA, more than 600bp long. The predicted protein structure contains an N-terminal cytoplasmic domain, a transmembrane region, a coiled-coil motif, and two putative catalytic domains. This catalytic domain has closest homology to GT8 glycosyltransferase involved in lipooligosaccharide synthesis. Pssm-ID: 133053 Cd Length: 280 Bit Score: 79.06 E-value: 1.70e-16
