Kojibiose phosphorylase

From Wikipedia, the free encyclopedia

In enzymology, a kojibiose phosphorylase (EC 2.4.1.230) is an enzyme that catalyzes the chemical reaction

2-alpha-D-glucosyl-D-glucose + phosphate $\rightleftharpoons$ D-glucose + beta-D-glucose 1-phosphate

Thus, the two substrates of this enzyme are 2-alpha-D-glucosyl-D-glucose and phosphate, whereas its two products are D-glucose and beta-D-glucose 1-phosphate.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is 2-alpha-D-glucosyl-D-glucose:phosphate beta-D-glucosyltransferase.
