Thus, the two substrates of this enzyme are primary alcohol and O2, whereas its two products are aldehyde and H2O2.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of the donor with oxygen as the acceptor. The systematic name of this enzyme class is alcohol:oxygen oxidoreductase. This enzyme is also called ethanol oxidase. It employs one cofactor, FAD.
Structural studies
As of late 2007, 9 structures have been solved for this class of enzymes, with PDB accession codes 1AHU, 1AHV, 1AHZ, 1VAO, 1W1J, 1W1K, 1W1L, 1W1M, and 2VAO.
