Identifier
TETX
Protein name
RecName: Full=Flavin-dependent monooxygenase;
AltName: Full=TetX monooxygenase;
Short=TetX;
EC 1.14.13.-;

Comments [?]

Function An FAD-requiring monooxygenase active on some tetracycline antibiotic derivatives, which leads to their inactivation. Hydroxylates carbon 11a of tetracycline and some analogs.
Catalytic activity RHEA:61444: a tetracycline + H(+) + NADPH + O2 = an 11a-hydroxytetracycline + H2O + NADP(+)
Cofactor FAD
Subunit Monomer.
Subcellular location Cytoplasm.
Domain Consists of an N-terminal FAD-binding domain with a Rossman fold and a C-terminal substrate-binding domain.
Similarity Belongs to the aromatic-ring hydroxylase family. TetX subfamily.

Comments Other TetX proteins able to modify tetracycline and its analogs have been isolated from Mycobacterium abscessus and soil bacteria. These proteins are not members of this family. The proteins from soil bacteria modify a different position on the antibiotic and generate a different product.
