2,4'-dihydroxyacetophenone Dioxygenase

Post by hanlin »

In enzymology, a 2,4'-dihydroxyacetophenone dioxygenase (EC 1.13.11.41) is an enzyme that catalyzes the chemical reaction
2,4'-dihydroxyacetophenone + O2 4-hydroxybenzoate + formate
Thus, the two substrates of this enzyme are 2,4'-dihydroxyacetophenoneand O2, whereas its two products are 4-hydroxybenzoate and formate.
This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O2. The systematic name of this enzyme class is 2,4'-dihydroxyacetophenone oxidoreductase (C-C-bond-cleaving). This enzyme is also called (4-hydroxybenzoyl)methanol oxygenase. This enzyme participates in bisphenol a degradation.
Both 2,4-Dihydroxyacetophenone and 2-Methyl-5,7-dihydroxychromone are phenolic ketones which cause the pH-dependent color changes of the secretion.
