Pyruvate decarboxylase (PDC) is a homo-tetramerase (ec.4.1.1.1) that catalyzes the decarboxylation of pyruvate to acetaldehyde carbon dioxide in the cytoplasm. It is also known as 2-oxate carboxylase and acetone decarboxylase. Under anaerobic conditions, this enzyme is part of the fermentation process of yeast (especially saccharomyces saccharomyces), which produces ethanol by fermentation. Pyruvate decarboxylase starts this process by converting pyruvate into acetaldehyde and carbon dioxide. Pyruvate decarboxylase relies on cofactors thiamine pyrophosphate (TPP) and magnesium. This enzyme should not be mistaken for an unrelated pyruvate dehydrogenase, a REDOX enzyme (EC 1.2.4.1) that catalyzes oxidative decarboxylation of pyruvate to acetyl-CoA.
