In enzymology a DNA alpha-glucosyltransferase (EC 2.4.1.26) 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.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:DNA alpha-D-glucosyltransferase.
