FunFam 5: Pyruvate dehydrogenase E1 component

Please note: GO 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.

There are 8 GO terms relating to "molecular function"

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.

Cytosolic pyruvate dehydrogenase complex GO:0045250
Complex that carries out the oxidative decarboxylation of pyruvate to form acetyl-CoA; comprises subunits possessing three catalytic activities: pyruvate dehydrogenase (E1), dihydrolipoamide S-acetyltransferase (E2), and dihydrolipoamide dehydrogenase (E3). Usually contains fewer subunits than its eukaryotic counterpart; for example, the E. coli complex contains 12 E1 dimers, 8 E2 trimers, and 6 E3 dimers arranged in highly symmetric cubic order.
