Protein

Fumarate hydratase class II

Gene

fumC

Organism
Synechococcus sp. (strain CC9311)
Status
Unreviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Involved in the TCA cycle. Catalyzes the stereospecific interconversion of fumarate to L-malate.UniRule annotation

Miscellaneous

There are 2 substrate-binding sites: the catalytic A site, and the non-catalytic B site that may play a role in the transfer of substrate or product between the active site and the solvent. Alternatively, the B site may bind allosteric effectors.UniRule annotation

Catalytic activityi

(S)-malate = fumarate + H2O.UniRule annotation

Pathwayi: tricarboxylic acid cycle

This protein is involved in step 1 of the subpathway that synthesizes (S)-malate from fumarate.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Fumarate hydratase class II (fumC)
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 (S)-malate from fumarate, 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.
