Entry
EC 1.14.13.48               Enzyme                                 
Name
(S)-limonene 6-monooxygenase;
(-)-limonene 6-hydroxylase;
(-)-limonene 6-monooxygenase;
(-)-limonene,NADPH:oxygen oxidoreductase (6-hydroxylating)
Class
Oxidoreductases;
Acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2;
With NADH or NADPH as one donor, and incorporation of one atom of oxygen into the other donor
BRITE hierarchy
Sysname
(S)-limonene,NADPH:oxygen oxidoreductase (6-hydroxylating)
Reaction(IUBMB)
(S)-limonene + NADPH + H+ + O2 = (-)-trans-carveol + NADP+ + H2O [RN:R02468]
Reaction(KEGG)
Substrate
(S)-limonene;
NADPH [CPD:C00005];
H+ [CPD:C00080];
O2 [CPD:C00007]
Product
(-)-trans-carveol [CPD:C00964];
NADP+ [CPD:C00006];
H2O [CPD:C00001]
Comment
High specificity, but NADH can act instead of NADPH, but more slowly. A heme-thiolate protein (P-450).
