| EC Number | 5.3.1.4 |
| CAS Registry Number | 9023-80-7 |
| Comments | Requires a divalent metal ion (the enzyme from the bacterium?Escherichia coli?prefers Mn2+) [2]. 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 [5]. The enzyme can also convert?D-galactose to?D-tagatose with lower efficiency [4]. |
| Cofactor | divalent cation |
| History | |
| Reactions | L-arabinose = L-ribulose. |
