FunFam 35890: 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.

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.

Cell wall GO:0005618

In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan; in protozoan parasites such as Giardia species, it's made of carbohydrates and proteins.
