Reaction catalysed

2 H(+) + narbomycin + O2 + 2 reduced [2Fe-2S]-[ferredoxin] = H2O + 2 oxidized [2Fe-2S]-[ferredoxin] + pikromycin
2 H(+) + narbomycin + O2 + 2 reduced [2Fe-2S]-[ferredoxin] = H2O + neopikromycin + 2 oxidized [2Fe-2S]-[ferredoxin]
4 H(+) + narbomycin + 2 O2 + 4 reduced [2Fe-2S]-[ferredoxin] = 2 H2O + novapikromycin + 4 oxidized [2Fe-2S]-[ferredoxin]
10-deoxymethymycin + 2 H(+) + O2 + 2 reduced [2Fe-2S]-[ferredoxin] = H2O + methymycin + 2 oxidized [2Fe-2S]-[ferredoxin]
10-deoxymethymycin + 2 H(+) + O2 + 2 reduced [2Fe-2S]-[ferredoxin] = H2O + neomethymycin + 2 oxidized [2Fe-2S]-[ferredoxin]
10-deoxymethymycin + 4 H(+) + 2 O2 + 4 reduced [2Fe-2S]-[ferredoxin] = 2 H2O + novamethymycin + 4 oxidized [2Fe-2S]-[ferredoxin]

Comment(s)

A cytochrome P450 (heme-thiolate) protein.
Involved in the biosynthesis of a number of bacterial macrolide antibiotics containing a desosamine glycoside unit.
With narbomycin it hydroxylates at either C-12 to give pikromycin or C-14 to give neopikromycin or both positions to give narvopikromycin.
With 10-deoxymethymycin it hydroxylates at either C-10 to give methymycin or C-12 to give neomethymycin or both positions to give novamethymycin.
Formerly EC 1.14.13.185.
