The metalloenzyme quercetin 2,3-dioxygenase (QueD) catalyzes the oxidative decomposition of the aromatic compound, quercetin. The most recently characterized example is a product of the bacterium Bacillus subtilis (BsQueD); all previous examples were fungal enzymes from the genus Aspergillus (AQueD). AQueD contains a single atom of Cu(II) per monomer. However, BsQueD, over expressed in Escherichia coli, contains Mn(II) and has two metal-binding sites, and therefore two possible active sites per monomer.
