In enzymology an acetolactate decarboxylase (EC 4.1.1.5) is an enzyme that catalyzes the chemical reaction(S)-2-hydroxy-2-methyl-3-oxobutanoate (R)-2-acetoin + CO2Hence this enzyme has one substrate (S)-2-hydroxy-2-methyl-3-oxobutanoate and two products (R)-2-acetoin and CO2.This enzyme belongs to the family of lyases specifically the carboxy-lyases which cleave carbon-carbon bonds.
