KEGG   ENZYME: 1.14.13.231
Entry
EC 1.14.13.231              Enzyme                                 
Name
tetracycline 11a-monooxygenase;
tetX (gene name)
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With NADH or NADPH as one donor, and incorporation of one atom of oxygen into the other donor
Sysname
tetracycline,NADPH:oxygen oxidoreductase (11a-hydroxylating)
Reaction(IUBMB)
tetracycline + NADPH + H+ + O2 = 11a-hydroxytetracycline + NADP+ + H2O [RN:R11449]
Reaction(KEGG)
R11449;
(other) R11525 R11526
Substrate
tetracycline [CPD:C06570];
NADPH [CPD:C00005];
H+ [CPD:C00080];
O2 [CPD:C00007]
Product
11a-hydroxytetracycline [CPD:C21391];
NADP+ [CPD:C00006];
H2O [CPD:C00001]
Comment
A flavoprotein (FAD). This bacterial enzyme confers resistance to all clinically relevant tetracyclines when expressed under aerobic conditions. The hydroxylated products are very unstable and lead to intramolecular cyclization and non-enzymic breakdown to undefined products.
