[[http://www.uniprot.org/uniprot/SUCD_ECOLI SUCD_ECOLI]] During aerobic metabolism it functions in the citric acid cycle, coupling the hydrolysis of succinyl-CoA to the synthesis of ATP and thus represents an important site of substrate-level phosphorylation. It can also function in the other direction for anabolic purposes, and this may be particularly important for providing succinyl-CoA during anaerobic growth when the oxidative route from 2-oxoglutarate is severely repressed. The alpha-subunit binds CoA, as well as ATP and catalyzes phosphoryl transfer to one of its histidine residues. The complete active site is probably located in the region of alpha-beta contact. [[http://www.uniprot.org/uniprot/SUCC_ECOLI SUCC_ECOLI]] During aerobic metabolism it functions in the citric acid cycle, coupling the hydrolysis of succinyl-CoA to the synthesis of ATP and thus represents an important site of substrate-level phosphorylation. It can also function in the other direction for anabolic purposes, and this may be particularly important for providing succinyl-CoA during anaerobic growth when the oxidative route from 2-oxoglutarate is severely repressed. The beta-subunit contains the attachment sites for succinate. The complete active site is probably located in the region of alpha-beta contact.
