Pyruvate decarboxylase is a homotetrameric enzyme ( EC 4.1.1.1) that catalyses the decarboxylation of pyruvic acid to acetaldehyde and carbon dioxide. It is also called 2-oxo-acid carboxylase, alpha-ketoacid carboxylase, and pyruvic decarboxylase [1]. In aerobic conditions, this enzyme is the first in a three enzyme complex known as ...
