In enzymology, a 1,3-beta-D-glucan phosphorylase (EC 2.4.1.97) is an enzyme that catalyzes the chemical reaction

(1,3-beta-D-glucosyl)n + phosphate \rightleftharpoons (1,3-beta-D-glucosyl)n-1 + alpha-D-glucose 1-phosphate

Thus, the two substrates of this enzyme are (1,3-beta-D-glucosyl)n and phosphate, whereas its two products are (1,3-beta-D-glucosyl)n-1 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 1,3-beta-D-glucan:phosphate alpha-D-glucosyltransferase. Other names in common use include laminarin phosphoryltransferase, 1,3-beta-D-glucan:orthophosphate glucosyltransferase, and laminarin phosphoryltransferase.
