Pathway: glyoxylate cycle

This protein is involved in step 1 of the subpathway that synthesizes (S)-malate from isocitrate.By similarity
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Isocitrate lyase (ICL 8)
  2. no protein annotated in this organism
This subpathway is part of the pathway glyoxylate cycle, which is itself part of Carbohydrate metabolism.

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.
