Accepted name: 3-hydroxy-4-methylanthranilyl-[aryl-carrier protein] 5-monooxygenase
Reaction: 3-hydroxy-4-methylanthranilyl-[aryl-carrier protein] + NADH + H+ + O2 = 3,5-dihydroxy-4-methylanthranilyl-[aryl-carrier protein] + NAD+ + H2O
Glossary: anthranilate = 2-aminobenzoate
Other name(s): sibG (gene name)
Systematic name: 3-hydroxy-4-methylanthranilyl-[aryl-carrier protein],NADH:oxygen oxidoreductase (5-hydroxylating)
Comments: A flavoprotein (FAD). The enzyme, characterized from the bacterium Streptosporangium sibiricum, is involved in the biosynthesis of the antitumor antibiotic sibiromycin. The enzyme is not active with free 3-hydroxy-4-methylanthranilate.
