L-fucose isomerase

Gene

fucI

Organism
Streptococcus pneumoniae serotype 4 (strain ATCC BAA-334 / TIGR4)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

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

Pathway: 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. no protein annotated in this organism
  3. no protein annotated in this organism
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.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
