L-fucose isomerase EC#: 5.3.1.25; ChemWhat Code: 1383225
| Product Name | L-fucose isomerase |
| Example Structure |  |
| Synonyms | D-Arabinose (L-Fucose) isomerase, D-Arabinose isomerase, EC 5.3.1.3, FcsI, FucI, Fucose isomerase, Isomerase, L-fucose, L-Fucose isomerase, L-fucose ketol-isomerase |
| EC Number | 5.3.1.25 |
| CAS Registry Number | |
| Comments | 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 from?Escherichia coli?can also convert?D-arabinose to?D-ribulose [1]. The enzyme from the thermophilic bacterium?Caldicellulosiruptor saccharolyticus?also converts?D-altrose to?D-psicose and?L-galactose to?L-tagatose [4]. |
| Cofactor | Mn2+ |
| History | |
| Reactions | L-fucopyranose = L-fuculose. |
