Rhodococcus erythropolis DCL14 contains a novel degradation pathway for limonene
Article Abstract:
A strain of Rhodococcus erythropolis, which can grow on limonene as a sole source of carbon and energy, contains a novel degradation pathway for limonene. This pathway for limonene in R erythropolis DCL14 begins with attack at the 1,2 double bond by an FAD-and NADH-dependent monooxygenase, which resembles two epoxide-forming monooxygenase activities described earlier. This epoxidation at the 1,2 double bond forms limonene-1,2-epoxide, which is subsequently converted to limonene-1,2-diol, 1-hydroxy-2-oxolimonene and 7-hydroxy-4-isopropenyl-7-methyl-2-oxo-oxepanone. This acid is further converted in the presence of coenzyme A and ATP.

Metabolism of carveol and dihydrocarveol in Rhodococcus erythropolis DCL14
Article Abstract:
Carveol and dihydrocarveol and their metabolism in Rhodococcus erythropolis DCL14 are discussed. R erythropolis DCL14 assimilates all stereoisomers of carveol and dihydrocarveol as its only source of carbon and energy and indiction experiments with cell grown on these two substances shoed high oxygen consumption rates with these and with carvone and dihydrocarvone. R. erythropolis DCL14 was found to metabolize the four diastereomers of carveol by oxidation to carvone. It is then stereospecifically reduced to (1R)-(iso)-dihydrocarvone. Dihydrocarveol enters the pathway and other reactions take place.

Genetic and biochemical characterization of a novel monoterpene epsilon-lactone hydrolase from Rhodococcus erythropolis DCL14
Article Abstract:
The properties of a monoterpene epsilon-lactone hydrolase from Rhodococcus erythropolis DCL14 are described. The corresponding gene has 43% similarity to some members of the GDXG family of lipolytic enzymes.
