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. 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 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.
