Protein

Succinate--CoA ligase [ADP-forming] subunit alpha, mitochondrial

Gene

tca-8

Organism
Neurospora crassa (strain ATCC 24698 / 74-OR23-1A / CBS 708.71 / DSM 1257 / FGSC 987)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Protein inferred from homologyi

Functioni

Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of ATP and thus represents the only step of substrate-level phosphorylation in the TCA. The alpha subunit of the enzyme binds the substrates coenzyme A and phosphate, while succinate binding and nucleotide specificity is provided by the beta subunit.UniRule annotation

Catalytic activityi

ATP + succinate + CoA = ADP + phosphate + succinyl-CoA.UniRule annotation

Pathwayi: tricarboxylic acid cycle

This protein is involved in step 1 of the subpathway that synthesizes succinate from succinyl-CoA (ligase route).UniRule annotation1 Publication
Proteins known to be involved in this subpathway in this organism are:
  1. Succinate--CoA ligase [ADP-forming] subunit alpha, mitochondrial (tca-8), Succinate--CoA ligase [ADP-forming] subunit beta, mitochondrial (tca-9)
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 succinate from succinyl-CoA (ligase route), 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.
