Comment(s)
  • Catalyzes one of the steps in the anhydrofructose pathway, which leads to the degradation of glycogen and starch via 1,5-anhydro-D- fructose.
  • The other enzymes involved in this pathway are EC 4.2.1.110, EC 4.2.1.111 and EC 4.2.2.13.
  • Ascopyrone P is an anti-oxidant.
  • Formerly EC 5.3.3.15.
