6-oxocamphor hydrolase (EC 3.7.1.18, OCH, camK (gene)) is an enzyme with systematic name bornane-2,6-dione hydrolase.[1][2][3] This enzyme catalyses the following chemical reaction

bornane-2,6-dione + H2O [math]\rightleftharpoons[/math] [(1S)-4-hydroxy-2,2,3-trimethylcyclopent-3-enyl]acetate

This enzyme is isolated from Rhodococcus sp.
