ENZYME entry: EC

Accepted Name
1,3-alpha-oligoglucan phosphorylase.
Reaction catalysed
[(1->3)-alpha-D-glucosyl](n) + phosphate <=> [(1->3)-alpha-D-glucosyl](n-1) + beta-D-glucose 1-phosphate
  • The enzyme, isolated from the bacterium Clostridium phytofermentans, catalyzes a reversible reaction.
  • Substrates for the phosphorolytic reaction are alpha-1,3-linked oligoglucans with a polymerisation degree of 3 or more.
  • Nigerose (i.e. 3-O-alpha-D-glucopyranosyl-D-glucopyranose) is not phosphorylyzed but can serve as substrate in the reverse direction (cf. EC
