In enzymology, a cellodextrin phosphorylase (EC 2.4.1.49) is an enzyme that catalyzes the chemical reaction
- (1,4-beta-D-glucosyl)n + phosphate (1,4-beta-D-glucosyl)n-1 + alpha-D-glucose 1-phosphate
Thus, the two substrates of this enzyme are (1,4-beta-D-glucosyl)n and phosphate, whereas its two products are (1,4-beta-D-glucosyl)n-1 and alpha-D-glucose 1-phosphate.
This enzyme belongs to GH (glycoside hydrolases) family 94. The systematic name of this enzyme class is 1,4-beta-D-oligo-D-glucan:phosphate alpha-D-glucosyltransferase. This enzyme is also called beta-1,4-oligoglucan:orthophosphate glucosyltransferase.
