KEGG   ENZYME: 1.14.19.49
Entry
EC 1.14.19.49               Enzyme                                 
Name
tetracycline 7-halogenase;
ctcP (gene name)
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With oxidation of a pair of donors resulting in the reduction of O2 to two molecules of water
Sysname
tetracycline:FADH2 oxidoreductase (7-halogenating)
Reaction(IUBMB)
tetracycline + FADH2 + chloride + O2 + H+ = 7-chlorotetracycline + FAD + 2 H2O [RN:R11478]
Reaction(KEGG)
R11478
Substrate
tetracycline [CPD:C06570];
FADH2 [CPD:C01352];
chloride [CPD:C00698];
O2 [CPD:C00007];
H+ [CPD:C00080]
Product
7-chlorotetracycline [CPD:C06571];
FAD [CPD:C00016];
H2O [CPD:C00001]
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).
