EC 1.17.99.8 Details

show Brenda entry

EC number

1.17.99.8

Accepted name

limonene dehydrogenase

Reaction

(1) (S)-limonene + H₂O + acceptor = (–)-perillyl alcohol + reduced acceptor;;(2) (R)-limonene + H₂O + acceptor = (+)-perillyl alcohol + reduced acceptor

Other name(s)

ctmAB (gene names)

Systematic name

limonene:acceptor oxidoreductase (7-hydroxylating)

Comment

Contains FAD. The enzyme, characterized from the bacterium Castellaniella defragrans 65Phen, hydroxylates the R- and S-enantiomers at a similar rate. The in vivo electron acceptor may be a heterodimeric electron transfer flavoprotein (ETF).
