ID 1.14.20.15 DE L-threonyl-[L-threonyl-carrier protein] 4-chlorinase. CA L-threonyl-[peptidyl-carrier protein] + chloride + 2-oxoglutarate + O2 + CA H(+) = 4-chloro-L-threonyl-[peptidyl-carrier protein] + succinate + CO2 + CA H2O. CC -!- The enzyme, characterized from the bacterium Pseudomonas syringae, CC participates in syringomycin E biosynthesis. CC -!- The enzyme is a specialized iron(II)/2-oxoglutarate-dependent CC oxygenase that catalyzes the chlorination of its substrate in a CC reaction that requires oxygen, chloride ions, ferrous iron and CC 2-oxoglutarate.
