6-oxocamphor hydrolase

UniProtKB accession:  Q93TU6

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the carbon-carbon bond cleavage of the bicyclic beta-diketone 6-oxocamphor via a retro-Claisen reaction to yield the optically active (2R,4S)-beta-campholinic acid. It is also able to cleave 2,2-disubstituted cyclohexa-1,3-diones such as 2-methyl-2-propylcyclohexa-1,3-dione and 2-methyl-2-butylcyclohexa-1,3-dione which result in racemic keto acid products. Transformations of the bicyclic diketone substrates bicyclo[2.2.1]heptane 2,6-dione and bicyclo[2.2.2]octane-2,6-dione yield (S)-keto acid products.
