1.14.15.33
Accepted name
pikromycin synthase
Reaction
(1) narbomycin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ + O2 = pikromycin + 2 oxidized ferredoxin [iron-sulfur] cluster + H2O;;(2) narbomycin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ + O2 = neopikromycin + 2 oxidized ferredoxin [iron-sulfur] cluster + H2O;;(3) narbomycin + 4 reduced ferredoxin [iron-sulfur] cluster + 4 H+ + 2 O2 = novapikromyin + 4 oxidized ferredoxin [iron-sulfur] cluster + 2 H2O;;(4) 10-deoxymethymycin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ + O2 = methymycin + 2 oxidized ferredoxin [iron-sulfur] cluster + H2O;;(5) 10-deoxymethymycin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ + O2 = neomethymycin + 2 oxidized ferredoxin [iron-sulfur] cluster + H2O;;(6) 10-deoxymethymycin + 4 reduced ferredoxin [iron-sulfur] cluster + 4 H+ + 2 O2 = novamethymycin + 4 oxidized ferredoxin [iron-sulfur] cluster + 2 H2O
Other name(s)
PikC,
CYP107L1
Systematic name
narbomycin,reduced ferredoxin:oxygen oxidoreductase (pikromycin-forming)
Comment
A cytochrome P-450 (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.
