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 Catalyzes the synthesis of acetyl-CoA from short-chain fatty acids (PubMed:16788062). Acetate is the preferred substrate (PubMed:16788062). Can also utilize propionate with a much lower affinity (By similarity). Provides acetyl-CoA that is utilized mainly for oxidation under ketogenic conditions (By similarity). Involved in thermogenesis under ketogenic conditions, using acetate as a vital fuel when carbohydrate availability is insufficient (By similarity).CATALYTIC ACTIVITY acetate + ATP + CoA = acetyl-CoA + AMP + diphosphateCATALYTIC ACTIVITY propanoate + ATP + CoA = propanoyl-CoA + AMP + diphosphateACTIVITY REGULATION Inhibited by acetylation at Lys-642 and activated by deacetylation mediated by the deacetylase SIRT3.SUBUNIT Interacts with SIRT3.INTERACTION Reversibly acetylated on Lys-642 (PubMed:16788062). The acetyl-CoA synthase activity is inhibited by acetylation and activated by deacetylation mediated by the deacetylase SIRT3.SIMILARITY Belongs to the ATP-dependent AMP-binding enzyme family.SEQUENCE CAUTION Sequencing errors.
