Enzyme Information
| 5.3.1.25 |
L-fucose isomerase.
based on mapping to UniProt P69922
L-fucopyranose = L-fuculose.
-!- The enzyme binds the closed form of the sugar and catalyzes ring opening to generate a form of open-chain conformation that facilitates the isomerization reaction, which proceeds via an ene- diol mechanism. -!- The enzyme from Escherichia coli can also convert D-arabinose to D-ribulose. -!- The enzyme from the thermophilic bacterium Caldicellulosiruptor saccharolyticus also converts D-altrose to D-psicose and L-galactose to L-tagatose.

| 5.3.1.3 |
D-arabinose isomerase.
based on mapping to UniProt P69922
D-arabinose = D-ribulose.
-!- The enzyme binds the closed form of the sugar and catalyzes ring opening to generate a form of open-chain conformation that facilitates the isomerization reaction, which proceeds via an ene- diol mechanism. -!- The enzyme catalyzes the aldose-ketose isomerization of several sugars. -!- Most enzymes also catalyze the reaction of EC 5.3.1.25. -!- The enzyme from the bacterium Falsibacillus pallidus also converts D-altrose to D-psicose. -!- Cf. EC 5.3.1.4.
