EC 1.14.13.215

Accepted name: protoasukamycin 4-monooxygenase

Reaction: protoasukamycin + NADH + H+ + O2 = 4-hydroxyprotoasukamycin + NAD+ + H2O

Glossary: asuE1 (gene name)

Systematic name: protoasukamycin,NADH:oxygen oxidoreductase (4-hydroxylating)

Comments: The enzyme, characterized from the bacterium Streptomyces nodosus subsp. asukaensis, is involved in the biosynthesis of the antibiotic asukamycin. Requires a flavin cofactor, with no preference among FMN, FAD or riboflavin. When flavin concentration is low, activity is enhanced by the presence of the NADH-dependent flavin-reductase AsuE2.
