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 reversible transfer of acyl groups from carnitine to coenzyme A (CoA) and regulates the acyl-CoA/CoA ratio. Also plays a crucial role in the transport of fatty acids for beta-oxidation (PubMed:15099582, PubMed:29395073). Responsible for the synthesis of short- and branched-chain acylcarnitines (PubMed:23485643). Active towards some branched-chain amino acid oxidation pathway (BCAAO) intermediates (PubMed:23485643). Trans-2-enoyl-CoAs and 2-methylacyl-CoAs are poor substrates (PubMed:23485643).CATALYTIC ACTIVITY (R)-carnitine + acetyl-CoA = O-acetyl-(R)-carnitine + CoACATALYTIC ACTIVITY propanoyl-CoA + (R)-carnitine = O-propanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY butanoyl-CoA + (R)-carnitine = O-butanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY hexanoyl-CoA + (R)-carnitine = O-hexanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY octanoyl-CoA + (R)-carnitine = O-octanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY decanoyl-CoA + (R)-carnitine = O-decanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY 3-methylbutanoyl-CoA + (R)-carnitine = O-3-methylbutanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY 2-methylpropanoyl-CoA + (R)-carnitine = O-isobutanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY 2-methylbutanoyl-CoA + (R)-carnitine = O-2-methylbutanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY acetoacetyl-CoA + (R)-carnitine = O-3-oxobutanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY 3-hydroxybutanoyl-CoA + (R)-carnitine = O-3-hydroxybutanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY 4,8-dimethylnonanoyl-CoA + (R)-carnitine = O-4,8-dimethylnonanoyl-(R)-carnitine + CoACATALYTIC ACTIVITY 2,6-dimethylheptanoyl-CoA + (R)-carnitine = O-2,6-dimethylheptanoyl-(R)-carnitine + CoABIOPHYSICOCHEMICAL PROPERTIES Monomer.SUBCELLULAR LOCATION Mostly in skeletal muscle, less in heart, liver and pancreas, only weakly detectable in brain, placenta, lung and kidney.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the carnitine/choline acetyltransferase family.
