Protein

L-fucose isomerase

Gene

fucI

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Converts the aldose L-fucose into the corresponding ketose L-fuculose. Is also able to convert D-arabinose into D-ribulose, but this isomerase has a higher affinity for fucose and fuculose than for arabinose and ribulose, respectively.

Catalytic activityi

L-fucopyranose = L-fuculose.1 Publication
D-arabinose = D-ribulose.1 Publication

Cofactori

Kineticsi

  1. KM=17 mM for L-fucose
  2. KM=35 mM for D-arabinose
  3. KM=1.4 mM for L-fuculose
  4. KM=11 mM for D-ribulose
