== Function ==
[https://www.uniprot.org/uniprot/TETX_BACT4 TETX_BACT4] An FAD-requiring monooxygenase active on tetracycline antibiotic derivatives, which leads to their inactivation (PubMed:15452119, PubMed:16128584). Hydroxylates carbon 11a of oxytetracycline and tigecycline (PubMed:15452119, PubMed:26097034). Acts on many tetracycline analogs (chlorotetracycline, demeclocycline, doxycycline, minocycline, oxytetracyclinee), probably by monooxygenization (PubMed:15452119, PubMed:16128584). Tigecycline, a new generation tetracycline antibiotic, is rendered less effective against E.coli by this monooxygenation, is much weaker at inhibiting translation in vitro and binds Mg(2+) considerably less well (PubMed:16128584, PubMed:26097034). Expression in E.coli BW25113 reduces its growth rate about 5%. The reaction probably proceeds by FAD reduction by NADPH and, second, hydroxylation of antibiotic in a ping-pong mechanism (PubMed:23236139). Degrades chlortetracycline, probably by monooxygenation (PubMed:15452119, PubMed:28481346). Slowly oxidizes anhydrotetracycline, the final substrate in tetracycline biosynthesis (PubMed:26097034).[HAMAP-Rule:MF_00845]<ref>PMID:15452119</ref> <ref>PMID:16128584</ref> <ref>PMID:23236139</ref> <ref>PMID:26097034</ref> <ref>PMID:28481346</ref>
