Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Cytosolic enzyme that catalyzes the carboxylation of acetyl-CoA to malonyl-CoA, the first and rate-limiting step of de novo fatty acid biosynthesis (PubMed:20457939, PubMed:20952656, PubMed:29899443). This is 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 (PubMed:20457939, PubMed:20952656, PubMed:29899443).CATALYTIC ACTIVITY hydrogencarbonate + acetyl-CoA + ATP = malonyl-CoA + ADP + phosphate + H(+)COFACTOR Binds 2 magnesium or manganese ions per subunit.COFACTOR Inhibited by phosphorylation (PubMed:16326698, PubMed:29899443). Citrate promotes oligomerization of the protein into filaments that correspond to the most active form of the carboxylase (PubMed:29899443). Inhibited by palmitoyl-CoA (PubMed:29899443).PATHWAY Lipid metabolism; malonyl-CoA biosynthesis; malonyl-CoA from acetyl-CoA: step 1/1.SUBUNIT Monomer, homodimer, and homotetramer (PubMed:20952656, PubMed:29899443). Can form filamentous polymers (PubMed:20457939, PubMed:20952656, PubMed:29899443). Interacts in its inactive phosphorylated form with the BRCT domains of BRCA1 which prevents ACACA dephosphorylation and inhibits lipid synthesis (PubMed:12360400, PubMed:16326698, PubMed:18452305, PubMed:29899443). Interacts with MID1IP1; interaction with MID1IP1 promotes oligomerization and increases its activity (PubMed:20457939).INTERACTION Expressed in brain, placenta, skeletal muscle, renal, pancreatic and adipose tissues; expressed at low level in pulmonary tissue; not detected in the liver.DOMAIN Consists of an N-terminal biotin carboxylation/carboxylase (BC) domain that catalyzes the ATP-dependent transient carboxylation of the biotin covalently attached to the central biotinyl-binding/biotin carboxyl carrier (BCC) domain (Probable). The C-terminal carboxyl transferase (CT) domain catalyzes the transfer of the carboxyl group from carboxylated biotin to acetyl-CoA to produce malonyl-CoA (Probable).PTM Phosphorylation on Ser-1263 is required for interaction with BRCA1.PTM Phosphorylation at Ser-80 by AMPK inactivates enzyme activity.PTM The biotin cofactor is covalently attached to the central biotinyl-binding domain and is required for the catalytic activity.DISEASE The disease is caused by variants affecting the gene represented in this entry.ONLINE INFORMATION Acetyl-CoA carboxylase entry
