Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced iron-sulfur protein as one donor, and incorporation of one atom of oxygen into the other donor
A cytochrome P-450 (heme-thiolate) enzyme characterized from the bacterium Streptomyces atratus. The enzyme participates in biosynthesis of rufomycins, circular heptapeptides with anti-mycobacterial activity. The enzyme requires ferredoxin as its electron donor and catalyses a reaction in which nitric oxide is oxidized to a nitro group and inserted into L-tyrosine at the 3 position (not necessarily in this order).
