MeSH Heading: Pyruvate Decarboxylase
Tree Number(s): D08.811.520.224.125.750
Unique ID: D011767
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D011767
Scope Note: Catalyzes the decarboxylation of an alpha keto acid to an aldehyde and carbon dioxide. Thiamine pyrophosphate is an essential cofactor. In lower organisms, which ferment glucose to ethanol and carbon dioxide, the enzyme irreversibly decarboxylates pyruvate to acetaldehyde. EC 4.1.1.1.
Entry Term(s): 2-Oxo Acid Carboxy-Lyase; Pyruvic Decarboxylase; alpha-Carboxylase; alpha-Ketoacid Carboxylase
