In [[enzymology]], a '''1,3-beta-D-glucan phosphorylase''' ({{EC number|2.4.1.97}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]<br />
<br />
:(1,3-beta-D-glucosyl)n + phosphate <math>\rightleftharpoons</math> (1,3-beta-D-glucosyl)n-1 + alpha-D-glucose 1-phosphate<br />
<br />
Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[(1,3-beta-D-glucosyl)n]] and [[phosphate]], whereas its two [[product (chemistry)|products]] are [[(1,3-beta-D-glucosyl)n-1]] and [[alpha-D-glucose 1-phosphate]].<br />
<br />
This enzyme belongs to the family of [[glycosyltransferase]]s, 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'''. <br />
