Sysname
tetracycline:FADH2 oxidoreductase (7-halogenating)
Reaction(IUBMB)
tetracycline + FADH2 + chloride + O2 + H+ = 7-chlorotetracycline + FAD + 2 H2O [RN:
R11478 ]

Comment
The enzyme, characterized from the bacterium Streptomyces aureofaciens, is a member of the flavin-dependent halogenase family. The enzyme forms a lysine chloramine intermediate on an internal lysine residue before transferring the chlorine to the substrate. It is stereo-selective for the 4S (natural) isomer of tetracycline. FADH2 is provided by a dedicated EC
1.5.1.36 , flavin reductase (NADH).
