Dextrin dextranase

From Wikipedia, the free encyclopedia

In enzymology, a dextrin dextranase (EC 2.4.1.2) is an enzyme that catalyzes the chemical reaction

(1,4-alpha-D-glucosyl)n + (1,6-alpha-D-glucosyl)m (1,4-alpha-D-glucosyl)n-1 + (1,6-alpha-D-glucosyl)m⁺1

Thus, the two substrates of this enzyme are (1,4-alpha-D-glucosyl)n and (1,6-alpha-D-glucosyl)m, whereas its two products are (1,4-alpha-D-glucosyl)n-1 and (1,6-alpha-D-glucosyl)m+1.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is 1,4-alpha-D-glucan:1,6-alpha-D-glucan 6-alpha-D-glucosyltransferase. Other names in common use include dextrin 6-glucosyltransferase, and dextran dextrinase.
