2.4.1.334 |
| Accepted name: |
1,3-α-oligoglucan phosphorylase |
| Reaction: |
[(1→3)-α-D-glucosyl]n + phosphate = [(1→3)-α-D-glucosyl]n-1 + β-D-glucose 1-phosphate |
| Systematic name: |
1,3-α-D-glucan:phosphate β-D-glucosyltransferase |
| Comments: |
The enzyme, isolated from the bacterium Clostridium phytofermentans, catalyses a reversible reaction. Substrates for the phosphorolytic reaction are α-1,3-linked oligoglucans with a polymerisation degree of 3 or more. Nigerose (i.e. 3-O-α-D-glucopyranosyl-D-glucopyranose) is not phosphorylyzed but can serve as substrate in the reverse direction (cf. EC 2.4.1.279, nigerose phosphorylase). |
