Accepted name:
1,8-cineole 2-endo-monooxygenase
Other names:
Systematic name:
1,8-cineole,[reduced flavodoxin]:oxygen oxidoreductase (2-endo-hydroxylating)




A cytochrome P450 (heme-thiolate) protein that uses a flavodoxin-like redox partner to reduce the heme iron. Isolated from the bacterium Citrobacter braakii, which can use 1,8-cineole as the sole source of carbon. Formerly EC
