Title:

HO-dependent substrate oxidation by an engineered diiron site in a bacterial hemerythrin.

Journal:

Chem Commun (Camb). 2014 Jan 8.

Abstract:

The O2-binding carboxylate-bridged diiron site in DcrH-Hr was engineered in an effort to perform the H2O2-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 H2O2.
