FunFam 6: Acetyltransferase component of pyruvate dehydrogen...

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Dihydrolipoyllysine-residue acetyltransferase. [EC: 2.3.1.12]
Acetyl-CoA + enzyme N(6)-(dihydrolipoyl)lysine = CoA + enzyme N(6)- (S-acetyldihydrolipoyl)lysine.
  • A multimer (24-mer or 60-mer, depending on the source) of this enzyme forms the core of the pyruvate dehydrogenase multienzyme complex, and binds tightly both EC 1.2.4.1 and EC 1.8.1.4.
  • The lipoyl group of this enzyme is reductively acetylated by EC 1.2.4.1, and the only observed direction catalyzed by EC 2.3.1.12 is that where the acetyl group is passed to coenzyme A.
