Lipoate–protein ligase (, ''LplA'', ''lipoate protein ligase'', ''lipoate–protein ligase A'', ''LPL'', ''LPL-B'') is an
enzyme
An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different mol ...
