Class of enzymes

Pyruvate decarboxylase is an enzyme (EC 4.1.1.1) that catalyses the decarboxylation of pyruvic acid to acetaldehyde. It is also called 2-oxo-acid carboxylase, alpha-ketoacid carboxylase, and pyruvic decarboxylase.[1] In anaerobic conditions, this enzyme participates in the fermentation process that occurs in yeast, especially of the genus Saccharomyces, to produce ethanol by fermentation. It is also present in some species of fish (including goldfish and carp) where it permits the fish to perform ethanol fermentation (along with lactic acid fermentation) when oxygen is scarce.[2] Pyruvate decarboxylase starts this process by converting pyruvate into acetaldehyde and carbon dioxide.[3] Pyruvate decarboxylase depends on cofactors thiamine pyropho...
