GONUTS is under stress! The website is currently experiencing long-wait times and frequent time-outs due to the record number of students, groups, and annotations related to CACAO this semester. We are currently working on increasing performance -- please accept our apologies for the technical difficulties.
You can help reduce stress on the server by:
- not reloading pages frequently - this just adds
- opening links in new windows (so you can read the old page)
Category:GO:0005967 ! mitochondrial pyruvate dehydrogenase complex
name: mitochondrial pyruvate dehydrogenase complex
namespace: cellular_component
def: "Complex that carries out the oxidative decarboxylation of pyruvate to form acetyl-CoA in eukaryotes; includes subunits possessing three catalytic activities: pyruvate dehydrogenase (E1), dihydrolipoamide S-acetyltransferase (E2), and dihydrolipoamide dehydrogenase (E3). The This Eukaryotic form usually contains more subunits than its bacterial counterpart; for example, one known complex contains 30 E1 dimers, 60 E2 monomers, and 6 E3 dimers as well as a few copies of pyruvate dehydrogenase kinase and pyruvate dehydrogenase phosphatase." [GOC:mtg_sensu, ISBN:0471331309, ISBN:0716720094]
comment: Note that this term represents a location and not a function; the activity possessed by this complex is mentioned in the definition for the purpose of describing and distinguishing the complex. The functions of this complex are represented by the molecular function terms 'pyruvate dehydrogenase (lipoamide) activity ; GO:0004739', 'dihydrolipoamide S-acetyltransferase activity ; GO:0004742', and 'dihydrolipoamide dehydrogenase activity ; GO:0004148'.
