Other name(s): | TcmG; ElmG; tetracenomycin A2,NAD(P)H:O2 oxidoreductase (tetracenomycin C forming) | ||||||
Systematic name: | tetracenomycin A2,NADPH:oxygen oxidoreductase (tetracenomycin-C-forming) | ||||||
Comments: | Isolated from the bacterium Streptomyces glaucescens. The enzyme was also isolated from the bacterium Streptomyces olivaceus, where it acts on 8-demethyltetracenomycin A2 (tetracenomycin B2) as part of elloramycin biosynthesis. The reaction involves a monooxygenase reaction which is followed by a dioxygenase reaction giving a gem-diol and an epoxide. Water opens the epoxide giving two hydroxy groups. The gem-diol eliminates water to give a ketone which is then reduced to a hydroxy group. | ||||||
