Hexosyltransferases are a type of glycosyltransferase that catalyze the transfer of a hexose.
Examples include:
They are classified under EC number 2.4.1.

In enzymology, a 1,4-alpha-glucan 6-alpha-glucosyltransferase is an enzyme that catalyzes the chemical reaction that transfers an alpha-D-glucosyl residue in a 1,4-alpha-D-glucan to the primary hydroxyl group of glucose or 1,4-alpha-D-glucan.
In enzymology, a cellobiose phosphorylase is an enzyme that catalyzes the chemical reaction
In enzymology, a dolichyl-phosphate beta-D-mannosyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, a dolichyl-phosphate-mannose-protein mannosyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, a flavone 7-O-beta-glucosyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, an alternansucrase is an enzyme that catalyzes a chemical reaction that transfers an alpha-D-glucosyl residue from sucrose alternately to the 6- and 3-positions of the non-reducing terminal residue of an alpha-D-glucan, thereby creating a glucan with alternating alpha-1,6- and alpha-1,3-bonds. The name "alternan" was coined in 1982 for the glucan based on its alternating linkage structure.

In enzymology, a DNA alpha-glucosyltransferase is an enzyme that catalyzes the chemical reaction in which an alpha-D-glucosyl residue is transferred from UDP-glucose to a hydroxymethylcytosine residue in DNA.
In enzymology, a glucosyl-DNA beta-glucosyltransferase is an enzyme that catalyzes the chemical reaction in which a beta-D-glucosyl residue is transferred from UDP-glucose to a glucosylhydroxymethylcytosine residue in DNA. This enzyme resembles DNA beta-glucosyltransferase in that respect.
In enzymology, a lipopolysaccharide glucosyltransferase II is an enzyme that catalyzes the chemical reaction

Peptidoglycan glycosyltransferase is an enzyme used in the biosynthesis of peptidoglycan. It transfers a disaccharide-peptide from a donor substrate to synthesize a glycan chain.
In enzymology, a xyloglucan 4-glucosyltransferase is an enzyme that catalyzes the chemical reaction in which a beta-D-glucosyl residue is transferred from UDP-glucose to another glucose residue in xyloglucan, linked by a beta-1,4-D-glucosyl-D-glucose bond.
In enzymology, a xyloglucan:xyloglucosyl transferase (EC 2.4.1.207) is an enzyme that catalyzes the chemical reaction in which a beta-(1,4) bond in the backbone of a xyloglucan in broken; the xyloglucanyl segment is then transferred to the O4 of the non-reducing terminal glucose residue of either xyloglucan or an oligosaccharide thereof.
In enzymology, a phosphatidylinositol alpha-mannosyltransferase is an enzyme that catalyzes the chemical reaction in which at least one alpha-D-mannose residues are transferred from GDP-mannose to positions 6, 2 and others in 1-phosphatidyl-myo-inositol.
In enzymology, an oligosaccharide 4-alpha-D-glucosyltransferase is an enzyme that catalyzes the chemical reaction in which the non-reducing terminal alpha-D-glucose residue is transferred from a 1,4-alpha-D-glucan to the 4-position of an alpha-D-glucan. This enzyme is useful in hydrolyzing oligosaccharides.
In enzymology, an O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase is an enzyme that catalyzes the chemical reaction in which a beta-D-GlcNAc residue is transferred from UDP-D-GlcNAc to the fucose residue of a fucosylated protein.
In enzymology, a glycolipid 2-alpha-mannosyltransferase is an enzyme that catalyzes the chemical reaction in which an alpha-D-mannosyl residue is transferred from GDP-mannose to lipid-linked oligosaccharide, being attached by an alpha-1,2-D-mannosyl-D-mannose bond.
In enzymology, a glycolipid 3-alpha-mannosyltransferase is an enzyme that catalyzes the chemical reaction in which an alpha-D-mannosyl residue is transferred from GDP-mannose to a lipid-linked oligosaccharide, being attached by an alpha-1,3-D-mannosyl-D-mannose bond.
