H(2)O(2)-dependent substrate oxidation by an engineered diiron site in a bacterial hemerythrin

The O(2)-binding carboxylate-bridged diiron site in DcrH-Hr was engineered in an effort to perform the H(2)O(2)-dependent oxidation of external substrates. A His residue was introduced near the diiron site in place of a conserved residue, Ile119. The I119H variant promotes the oxidation of guaiacol...

Descripción
Sumario:The O(2)-binding carboxylate-bridged diiron site in DcrH-Hr was engineered in an effort to perform the H(2)O(2)-dependent oxidation of external substrates. A His residue was introduced near the diiron site in place of a conserved residue, Ile119. The I119H variant promotes the oxidation of guaiacol and 1,4-cyclohexadiene upon addition of H(2)O(2).
