Oligosaccharide 4-alpha-D-glucosyltransferase

From Wikipedia, the free encyclopedia

In enzymology, an oligosaccharide 4-alpha-D-glucosyltransferase (EC 2.4.1.161) 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.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is 1,4-alpha-D-glucan:1,4-alpha-D-glucan 4-alpha-D-glucosyltransferase. Other names in common use include amylase III, and 1,4-alpha-glucan:1,4-alpha-glucan 4-alpha-glucosyltransferase.
