Comment
The enzyme is involved in the malolactic fermentation of wine, which results in a natural decrease in acidity and favorable changes in wine flavors. It has been purified from several lactic acid bacteria, including Leuconostoc mesenteroides [1], Lactobacillus plantarum [2], and Oenococcus oeni [3,4]. The enzyme contains a tightly bound NAD+ cofactor and requires Mn2+.
