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 Biotin-attachment subunit of the 3-methylcrotonyl-CoA carboxylase, an enzyme that catalyzes the conversion of 3-methylcrotonyl-CoA to 3-methylglutaconyl-CoA, a critical step for leucine and isovaleric acid catabolism.CATALYTIC ACTIVITY 3-methylbut-2-enoyl-CoA + hydrogencarbonate + ATP = 3-methyl-(2E)-glutaconyl-CoA + ADP + phosphate + H(+)COFACTOR Amino-acid degradation; L-leucine degradation; (S)-3-hydroxy-3-methylglutaryl-CoA from 3-isovaleryl-CoA: step 2/3.SUBUNIT Probably a dodecamer composed of six biotin-containing alpha subunits (MCCC1) and six beta (MCCC2) subunits (PubMed:17360195). Interacts (via the biotin carboxylation domain) with SIRT4 (PubMed:23438705).INTERACTION Acetylated.DISEASE The disease is caused by variants affecting the gene represented in this entry.SEQUENCE CAUTION Extended N-terminus.
