Ligand Discrimination in Myoglobin from Linear-Scaling DFT+U
Myoglobin modulates the binding of diatomic molecules to its heme group via hydrogen-bonding and steric interactions with neighboring residues, and is an important benchmark for computational studies of biomolecules. We have performed calculations on the h ...
2012On the enzymatic activity of catalase: an iron L-edge X-ray absorption study of the active centre
Catalase and methaemoglobin have very similar haem groups, which are both ferric, yet catalase decomposes hydrogen peroxide to water and oxygen very efficiently, while methaemoglobin does not. Structural studies have attributed this behaviour to their diff ...
Royal Society of Chemistry2010Probing the Electronic Structure of the Hemoglobin Active Center in Physiological Solutions
Soft-x-ray absorption spectroscopy at the L2,3 edge of the iron center in bovine Hb and hemin under physiol. conditions is reported for the first time. Spectra of the same compds. in solid form are presented for comparison. Striking differences in the elec ...
