PMID:15890657 PMID:6765947
Propionyl-CoA carboxylase catalyzes the carboxylation of propionyl-CoA/propanoyl-CoA to D-methylmalonyl-CoA/(S)-methylmalonyl-CoA .
PMID:15890657 PMID:6765947
Within the holoenzyme, the alpha subunit catalyzes the ATP-dependent carboxylation of the biotin carried by the biotin carboxyl carrier (BCC) domain, while the beta subunit then transfers the carboxyl group from carboxylated biotin to propionyl-CoA (By similarity). Propionyl-CoA carboxylase also significantly acts on butyryl-CoA/butanoyl-CoA, which is converted to ethylmalonyl-CoA/(2S)-ethylmalonyl-CoA at a much lower rate .
PMID:6765947
Other alternative minor substrates include (2E)-butenoyl-CoA/crotonoyl-CoA (By similarity)
PMID:16854592 PMID:19236960 PMID:19900410 PMID:20457939 PMID:20952656 PMID:26976583
Catalyzes a 2 steps reaction starting with the ATP-dependent carboxylation of the biotin carried by the biotin carboxyl carrier (BCC) domain followed by the transfer of the carboxyl group from carboxylated biotin to acetyl-CoA .
PMID:19236960 PMID:20457939 PMID:20952656 PMID:26976583
Through the production of malonyl-CoA that allosterically inhibits carnitine palmitoyltransferase 1 at the mitochondria, negatively regulates fatty acid oxidation (By similarity). Together with its cytosolic isozyme ACACA, which is involved in de novo fatty acid biosynthesis, promotes lipid storage (By similarity)

PMID:10329687 PMID:15561972 PMID:19211916 PMID:20980265 PMID:21570947 PMID:22015582 PMID:25809983 PMID:25971966 PMID:27904971 PMID:28052864 PMID:31754459
Functions as a Na(+)-coupled substrate symporter where the stoichiometry of Na(+):substrate is 2:1, creating an electrochemical Na(+) gradient used as driving force for substrate uptake .
PMID:10329687 PMID:20980265
Required for biotin and pantothenate uptake in the intestine across the brush border membrane .
PMID:19211916
Plays a role in the maintenance of intestinal mucosa integrity, by providing the gut mucosa with biotin (By similarity). Contributes to the luminal uptake of biotin and pantothenate into the brain across the blood-brain barrier PMID:25809983
PMID:14966140 PMID:15090606 PMID:16729224 PMID:16805814 PMID:17178845 PMID:17245649 PMID:17526579 PMID:20211600 PMID:30604288
Catalyzes passive carrier mediated diffusion of iodide .
PMID:12107270
Mediates iodide transport from the thyrocyte into the colloid lumen through the apical membrane .
PMID:12107270
May be responsible for the absorption of D-lactate and monocarboxylate drugs from the intestinal tract .
PMID:17245649
Acts as a tumor suppressor, suppressing colony formation in colon cancer, prostate cancer and glioma cell lines .
PMID:12829793 PMID:15867356 PMID:18037591
May play a critical role in the entry of L-lactate and ketone bodies into neurons by a process driven by an electrochemical Na(+) gradient and hence contribute to the maintenance of the energy status and function of neurons .
PMID:16805814
Mediates sodium-coupled electrogenic transport of pyroglutamate (5-oxo-L-proline) .
PMID:20211600
Can mediate the transport of chloride, bromide, iodide and nitrate ions when the external concentration of sodium ions is reduced PMID:19864324
