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:

L-fucose isomerase (fucI)
no protein annotated in this organism
no protein annotated in this organism

This subpathway is part of the pathway L-fucose degradation, which is itself part of Carbohydrate degradation.

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 one 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.
