Chain A   (ALDC_BREBE | P23616)
molecular function
    GO:0047605    acetolactate decarboxylase activity    Catalysis of the reaction: (S)-2-hydroxy-2-methyl-3-oxobutanoate = (R)-2-acetoin + CO2.
    GO:0016831    carboxy-lyase activity    Catalysis of the nonhydrolytic addition or removal of a carboxyl group to or from a compound.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
biological process
    GO:0045151    acetoin biosynthetic process    The chemical reactions and pathways resulting in the formation of acetoin, 3-hydroxy-2-butanone.
