Functioni

Miscellaneous

Citrate synthase is found in nearly all cells capable of oxidative metabolism.

Catalytic activityi

Acetyl-CoA + H2O + oxaloacetate = citrate + CoA.PROSITE-ProRule annotation

Pathwayi: tricarboxylic acid cycle

This protein is involved in step 1 of the subpathway that synthesizes isocitrate from oxaloacetate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Citrate synthase, mitochondrial (citA)
  2. Aconitate hydratase, mitochondrial (acoA)
This subpathway is part of the pathway tricarboxylic acid 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 isocitrate from oxaloacetate, the pathway tricarboxylic acid 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 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.
