DE   L-tryptophan 4-nitrase.
AN   4-nitro-L-tryptophane synthase.
CA   nitric oxide + L-tryptophan + reduced [2Fe-2S]-[ferredoxin] + O2 + H(+) =
CA   4-nitro-L-tryptophan zwitterion + oxidized [2Fe-2S]-[ferredoxin] + H2O.
CC   -!- A cytochrome P450 (heme-thiolate) enzyme characterized from the
CC       bacterium Streptomyces turgidiscabies.
CC   -!- The enzyme participates in biosynthesis of thaxtomins, cyclic
CC       dipeptides formed from the condensation of 4-nitro-L-tryptophan and
CC       L-phenylalanine that have phytotoxic properties.
CC   -!- The enzyme requires ferredoxin as its electron donor and catalyzes a
CC       reaction in which nitric oxide is oxidized to a nitro group and
CC       inserted into L-tryptophan at the 4 position (not necessarily in this
CC       order).
