Protein

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

Gene

SUCLG1

Organism
Bos taurus (Bovine)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP 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 specificity for either ATP or GTP is provided by different beta subunits.UniRule annotation

Catalytic activityi

ATP + succinate + CoA = ADP + phosphate + succinyl-CoA.UniRule annotation
GTP + succinate + CoA = GDP + 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 annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Succinate--CoA ligase [GDP-forming] subunit beta, mitochondrial (SUCLG2), Succinate--CoA ligase [ADP-forming] subunit beta, mitochondrial (SUCLA2), Succinate--CoA ligase [ADP/GDP-forming] subunit alpha, mitochondrial (SUCLG1)
This subpathway is part of the pathway tricarboxylic acid cycle, which is itself part of Carbohydrate metabolism.

Interactioni

Subunit structurei

Heterodimer of an alpha and a beta subunit. Different beta subunits determine nucleotide specificity. Together with the ATP-specific beta subunit SUCLA2, forms an ADP-forming succinyl-CoA synthetase (A-SCS). Together with the GTP-specific beta subunit SUCLG2 forms a GDP-forming succinyl-CoA synthetase (G-SCS).UniRule annotation

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.
