|Gene:||AKR1E2||Accession Number: G-14931 (MetaCyc)|
Species: Sus scrofa
Glycogen degradation gives rise to 1,5-anhydro-D-fructose which is then reduced to 1, 5-anhydro-D-glucitol in animal livers by an NADPH-dependent enzyme [Sakuma98]. This two step irreversible production of metabolically inactive 1, 5-anhydro-D-glucitol constitutes a third glycogenolytic pathway and may play a role in the control of mammalian glycogen metabolism [Sakuma98].
Molecular Weight of Polypeptide: 34.1 kD (from nucleotide sequence), 38.0 kD (experimental) [Sakuma98 ]

Enzymatic reaction of: 4anhydrofructose reductase (1,5-anhydro-D-fructose reductase)
EC Number: 22.214.171.1243
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
The reaction is physiologically favored in the opposite direction.
