Acetolactate decarboxylase
Template:Short description Template:Infobox enzyme The enzyme acetolactate decarboxylase (Template:EnzExplorer) catalyzes the chemical reaction
- (S)-2-hydroxy-2-methyl-3-oxobutanoate (R)-2-acetoin + CO2
Hence, this enzyme has one substrate, (S)-2-hydroxy-2-methyl-3-oxobutanoate, and two products, (R)-2-acetoin and CO2.[1]
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 (S)-2-hydroxy-2-methyl-3-oxobutanoate carboxy-lyase [(R)-2-acetoin-forming]. Other names in common use include alpha-acetolactate decarboxylase, and (S)-2-hydroxy-2-methyl-3-oxobutanoate carboxy-lyase. This enzyme participates in butanoate metabolism and c5-branched dibasic acid metabolism.
