KEGG   ENZYME: 1.14.13.232
Entry
EC 1.14.13.232              Enzyme                                 
Name
6-methylpretetramide 4-monooxygenase
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
6-methylpretetramide,NADPH:oxygen oxidoreductase (4-hydroxylating)
Reaction(IUBMB)
6-methylpretetramide + NADPH + H+ + O2 = 4-hydroxy-6-methylpretetramide + NADP+ + H2O [RN:R05463]
Reaction(KEGG)
R05463;
(other) R09190
Substrate
6-methylpretetramide [CPD:C06629];
NADPH [CPD:C00005];
H+ [CPD:C00080];
O2 [CPD:C00007]
Product
4-hydroxy-6-methylpretetramide [CPD:C06628];
NADP+ [CPD:C00006];
H2O [CPD:C00001]
Comment
The enzyme, characterized from the bacterium Streptomyces rimosus, participates in the biosynthesis of tetracycline antibiotics. That bacterium possesses two enzymes that can catalyse the reaction - OxyE is the main isozyme, while OxyL has a lower activity. OxyL is bifunctional, and its main function is EC 1.14.13.233, 4-hydroxy-6-methylpretetramide 12a-monooxygenase. Contains FAD.
