In enzymology, a laminaribiose phosphorylase ({{EC number|2.4.1.31}}) is an enzyme that catalyzes the chemical reaction
3-beta-D-glucosyl-D-glucose + phosphateD-glucose + alpha-D-glucose 1-phosphate
Thus, the two substrates of this enzyme are 3-beta-D-glucosyl-D-glucose and phosphate, whereas its two products are D-glucose and alpha-D-glucose 1-phosphate.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is 3-beta-D-glucosyl-D-glucose:phosphate alpha-D-glucosyltransferase.
