ID 1.14.20.11 DE 3-[(Z)-2-isocyanoethenyl]-1H-indole synthase. CA (2S)-3-(1H-indol-3-yl)-2-isocyanopropanoate + 2-oxoglutarate + H(+) + CA O2 = 3-[(Z)-2-isocyanoethenyl]-1H-indole + 2 CO2 + H2O + succinate. CC -!- The enzyme, characterized from the cyanobacterium Fischerella ambigua CC UTEX 1903, participates in the biosynthesis of hapalindole-type CC alkaloids. CC -!- The enzyme catalyzes an Fe(2+), 2-oxoglutarate-dependent CC monooxygenation at C-3, which is followed by decarboxylation and CC dehydration, resulting in the generation of a cis C-C double bond. CC cf. EC 1.14.20.12. DR V5TD18, AMBI3_FISAU; //
