Acetolactate decarboxylase


In enzymology, an acetolactate decarboxylase is an enzyme that catalyzes the chemical reaction
Hence, this enzyme has one substrate, -2-hydroxy-2-methyl-3-oxobutanoate, and two products, -2-acetoin and CO2.
This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is -2-hydroxy-2-methyl-3-oxobutanoate carboxy-lyase . Other names in common use include alpha-acetolactate decarboxylase, and -2-hydroxy-2-methyl-3-oxobutanoate carboxy-lyase. This enzyme participates in butanoate metabolism and c5-branched dibasic acid metabolism.

Structural studies

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code.
