enzymology, a kojibiose phosphorylase ( EC 220.127.116.11) is an enzyme that catalyzes the chemical reaction
2-alpha-D-glucosyl-D-glucose + phosphate
D-glucose + beta-D-glucose 1-phosphate
Thus, the two
substrates of this enzyme are 2-alpha-D-glucosyl-D-glucose (kojibiose) 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.
