In enzymology, a beta-diketone hydrolase (EC 3.7.1.7) is an enzyme that catalyzes the chemical reaction
- nonane-4,6-dione + H2O pentan-2-one + butanoate
Thus, the two substrates of this enzyme are nonane-4,6-dione and H2O, whereas its two products are 2-pentanone and butanoate.
This enzyme belongs to the family of hydrolases, specifically those acting on carbon-carbon bonds in ketonic substances. The systematic name of this enzyme class is nonane-4,6-dione acylhydrolase. This enzyme is also called oxidized PVA hydrolase.
Structural studies
[edit]As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 2J5G and 2J5S.
