ID 1.14.20.14 DE hapalindole-type alkaloid chlorinase. CA (1) hapalindole U + chloride + 2-oxoglutarate + O2 + H(+) = hapalindole G CA + succinate + CO2 + H2O. CA (2) 12-epi-fischerindole U + chloride + 2-oxoglutarate + O2 + H(+) = CA 12-epi-fischerindole G + succinate + CO2 + H2O. CC -!- The enzyme, characterized from hapalindole-type alkaloids-producing CC cyanobacteria, is a specialized iron(II)/2-oxoglutarate-dependent CC oxygenase that catalyzes the chlorination of its substrates in a CC reaction that requires oxygen, chloride ions, ferrous iron and CC 2-oxoglutarate. //
