Molecule diagrams generated from .mol files obtained from the KEGG ftp site.

Other name(s): Arabinose isomerase. L-fucose isomerase.
Cofactor(s): Mn(2+).
Comments: 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.
