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 Dihydrolipoamide succinyltransferase (E2) component of the 2-oxoglutarate dehydrogenase complex. The 2-oxoglutarate dehydrogenase complex catalyzes the overall conversion of 2-oxoglutarate to succinyl-CoA and CO(2). The 2-oxoglutarate dehydrogenase complex is mainly active in the mitochondrion (PubMed:29211711, PubMed:30929736). A fraction of the 2-oxoglutarate dehydrogenase complex also localizes in the nucleus and is required for lysine succinylation of histones: associates with KAT2A on chromatin and provides succinyl-CoA to histone succinyltransferase KAT2A (PubMed:29211711).CATALYTIC ACTIVITY N(6)-[(R)-dihydrolipoyl]-L-lysyl-[protein] + succinyl-CoA = N(6)-[(R)-S(8)-succinyldihydrolipoyl]-L-lysyl-[protein] + CoACOFACTOR Binds 1 lipoyl cofactor covalently.PATHWAY Amino-acid degradation; L-lysine degradation via saccharopine pathway; glutaryl-CoA from L-lysine: step 6/6.PATHWAY Carbohydrate metabolism; tricarboxylic acid cycle.SUBUNIT The 2-oxoglutarate dehydrogenase complex is composed of OGDH (2-oxoglutarate dehydrogenase; E1), DLST (dihydrolipoamide succinyltransferase; E2), DLD (dihydrolipoamide dehydrogenase; E3) and the assembly factor KGD4 (By similarity). It contains multiple copies of the three enzymatic components (E1, E2 and E3). In the nucleus, the 2-oxoglutarate dehydrogenase complex associates with KAT2A (PubMed:29211711). Interacts with ABHD11; this interaction maintains the functional lipoylation of the 2-oxoglutarate dehydrogenase complex (PubMed:32792488).INTERACTION Mainly localizes in the mitochondrion. A small fraction localizes to the nucleus, where the 2-oxoglutarate dehydrogenase complex is required for histone succinylation.ALTERNATIVE PRODUCTS Disease susceptibility is associated with variants affecting the gene represented in this entry.SIMILARITY Belongs to the 2-oxoacid dehydrogenase family.
