L-fucose isomerase

Gene

fucI

Organism
Escherichia coli O157:H7
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Converts the aldose L-fucose into the corresponding ketose L-fuculose.UniRule annotation

Catalytic activityi

L-fucopyranose = L-fuculose.UniRule annotation

Cofactori

Mn2+UniRule annotation

Pathwayi: L-fucose degradation

This protein is involved in step 1 of the subpathway that synthesizes L-lactaldehyde and glycerone phosphate from L-fucose.UniRule annotation
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. L-fucose isomerase (fucI)
  2. L-fuculokinase (fucK)
  3. L-fuculose phosphate aldolase (fucA)
This subpathway is part of the pathway L-fucose degradation, which is itself part of Carbohydrate degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-lactaldehyde and glycerone phosphate from L-fucose, the pathway L-fucose degradation and in Carbohydrate degradation.
