Protein

Isocitrate lyase

Gene

ICL1

Organism
Candida albicans (Yeast)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the formation of succinate and glyoxylate from isocitrate, a key step of the glyoxylate cycle, which operates as an anaplerotic route for replenishing the tricarboxylic acid cycle. Required for growth on ethanol or acetate, but dispensable when fermentable carbon sources are available. Acts also on 2-methylisocitrate.By similarity

Catalytic activityi

Isocitrate = succinate + glyoxylate.By similarity
(2S,3R)-3-hydroxybutane-1,2,3-tricarboxylate = pyruvate + succinate.By similarity

Cofactori

Mg2+By similarity

Pathway:iglyoxylate cycle

This protein is involved in step 1 of the subpathway that synthesizes (S)-malate from isocitrate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Isocitrate lyase (ICL1)
  2. Malate synthase (MLS1)
This subpathway is part of the pathway glyoxylate cycle, which is itself part of Carbohydrate metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (S)-malate from isocitrate, the pathway glyoxylate cycle and in 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.
