Protein

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

Gene

sucD

Organism
Chlamydia trachomatis (strain D/UW-3/Cx)
Status
Unreviewed-Annotation score: -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 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 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 annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Succinate--CoA ligase [ADP-forming] subunit alpha (sucD), Succinate--CoA ligase [ADP-forming] subunit beta (sucC)
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.
