DFT analysis of axial and equatorial effects on heme-CO vibrational modes: applications to CooA and H-NOX heme sensor proteins

Determinants of the Fe-CO and C-O stretching frequencies in (imidazole) heme-CO adducts have been investigated via Density Functional Theory (DFT) analysis, in connection with puzzling characteristics of the heme sensor protein CooA, and of the H-NOX (Heme-Nitric Oxide and/or OXygen binding) family...
