ENZYME entry: EC 5.3.1.3

Accepted Name
D-arabinose isomerase
Alternative Name(s)
arabinose isomerase
L-fucose isomerase
Reaction catalysed
D-arabinose <=> D-ribulose
Comment(s)
  • 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.
