CC -!- FUNCTION: Heme-dependent dioxygenase that catalyzes the oxidative
CC cleavage of the L-tryptophan (L-Trp) pyrrole ring and converts L-
CC tryptophan to N-formyl-L-kynurenine. Catalyzes the oxidative cleavage
CC of the indole moiety. {ECO:0000255|HAMAP-Rule:MF_01972}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-tryptophan + O2 = N-formyl-L-kynurenine;
CC Xref=Rhea:RHEA:24536, ChEBI:CHEBI:15379, ChEBI:CHEBI:57912,
CC ChEBI:CHEBI:58629; EC=1.13.11.11; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01972};
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01972};
CC Note=Binds 1 heme group per subunit. {ECO:0000255|HAMAP-Rule:MF_01972};
CC -!- PATHWAY: Amino-acid degradation; L-tryptophan degradation via
CC kynurenine pathway; L-kynurenine from L-tryptophan: step 1/2.
CC {ECO:0000255|HAMAP-Rule:MF_01972}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01972}.
CC -!- SIMILARITY: Belongs to the tryptophan 2,3-dioxygenase family.
CC {ECO:0000255|HAMAP-Rule:MF_01972}.
