FunFam 13: Pyruvate dehydrogenase [ubiquinone]

There are 2 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
Pyruvate dehydrogenase (quinone). [EC: 1.2.5.1]
Pyruvate + ubiquinone + H(2)O = acetate + CO(2) + ubiquinol.
  • This bacterial enzyme is located on the inner surface of the cytoplasmic membrane and coupled to the respiratory chain via ubiquinone.
  • Does not accept menaquinone.
  • Activity is greatly enhanced by lipids.
  • Requires thiamine diphosphate.
  • The enzyme can also form acetoin.
