ENZYME entry: EC 5.3.1.4

Accepted Name
L-arabinose isomerase.
Reaction catalysed
L-arabinose <=> L-ribulose
Cofactor(s)
Divalent cation.
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 can also convert D-galactose to D-tagatose with lower efficiency.
