BRITE hierarchy
Sysname
1,8-cineole,[reduced flavodoxin]:oxygen oxidoreductase (2-endo-hydroxylating)
Reaction(IUBMB)
1,8-cineole + [reduced flavodoxin] + O2 = 2-endo-hydroxy-1,8-cineole + [oxidized flavodoxin] + H2O [RN:R08784]
Reaction(KEGG)
Substrate
1,8-cineole [CPD:C09844];
reduced flavodoxin [CPD:C02745];
O2 [CPD:C00007]
Product
2-endo-hydroxy-1,8-cineole [CPD:C03092];
oxidized flavodoxin [CPD:C02869];
H2O [CPD:C00001]
Comment
A cytochrome P-450 (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.
