EC 2.4.1.333     
Accepted name: 1,2-β-oligoglucan phosphorylase
Reaction: [(1→2)-β-D-glucosyl]n + phosphate = [(1→2)-β-D-glucosyl]n-1 + α-D-glucose 1-phosphate
Systematic name: 1,2-β-D-glucan:phosphate α-D-glucosyltransferase
Comments: The enzyme has been isolated from the bacterium Listeria innocua. It catalyses the reversible phosphorolysis of β-(1→2)-D-glucans. The minimum length of the substrate for the phosphorolytic reaction is 3 D-glucose units. In the synthetic reaction starting from sophorose and α-D-glucose 1-phosphate the average polymerisation degree is 39.
