ID 1.14.20.14 DE hapalindole-type alkaloid chlorinase. CA (1) 2-oxoglutarate + chloride + H(+) + hapalindole U + O2 = CO2 + H2O + CA hapalindole G + succinate. CA (2) 12-epi-fischerindole U + 2-oxoglutarate + chloride + H(+) + O2 = CA 12-epi-fischerindole G + CO2 + H2O + succinate. 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. //
