Unspecific peroxygenase (, ''aromatic peroxygenase'', ''mushroom peroxygenase'', ''haloperoxidase-peroxygenase'', ''Agrocybe aegerita peroxidase'') 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 ...
