Comment
Requires a divalent metal ion (the enzyme from the bacterium Escherichia coli prefers Mn2+). The enzyme binds the closed form of the sugar and catalyses ring opening to generate a form of open-chain conformation that facilitates the isomerization reaction, which proceeds via an ene-diol mechanism [3]. The enzyme catalyses the aldose-ketose isomerization of several sugars. Most enzymes also catalyse the reaction of EC
5.3.1.25 , L-fucose isomerase [3]. The enzyme from the bacterium Falsibacillus pallidus also converts D-altrose to D-psicose [4]. cf. EC
5.3.1.4 , L-arabinose isomerase.
