1.1.1.245	synthesis	synthesis of lactones from cycloalkanes. A heterologous pathway comprising enzymes with compatible kinetics is designed in Pseudomonas taiwanensis VLB120 enabling in-vivo cascade for synthesizing lactones from cycloalkanes. The respective pathway includes cytochrome P450 monooxygenase (CHX), cyclohexanol dehydrogenase (CDH), and cyclohexanone monooxygenase (CHXON) from Acidovorax sp. CHX100. Resting cells of the recombinant host Pseudomonas taiwanensis VLB120 convert cyclohexane, cyclohexanol, and cyclohexanone to epsilon-caprolactone at 22, 80-100, and 170 U/g cell dry weight, respectively. Cyclohexane (5 mM) is completely converted with a selectivity of 65% for epsilon-caprolactone formation in 2 h without accumulation of intermediate products	742146
