FTIR and Resonance Raman Studies of Nitric Oxide Binding to H93G Cavity Mutants of Myoglobin
Animals Nitric Oxide Imidazoles Myoglobin Enzyme Inhibitors Free Radical Scavengers Spectroscopy, Fourier Transform Infrared Spectrum Analysis, Raman Binding Sites Molecular Structure
2016/5/23
Nitric oxide (NO) binds to the myoglobin (Mb) cavity mutant, H93G, forming either a five- or six-coordinate Fe-NO complex. The H93G mutation eliminates the covalent attachment between the protein and ...
Resonance Raman Studies of Heme Axial Ligation in H93G Myoglobin
chemical vapor deposition diamond electron microscopy epitaxy iridium surface structure,morphology,roughness,and topography
2016/5/23
The resonant Raman active mode identified in numerous studies as the heme iron−histidine stretch has been systematically investigated in the Raman spectrum of 15 exogenous ligands to the heme ir...
The Role of the Distal and Proximal Protein Environments in Controlling the Ferric Spin State and in Stabilizing Thiolate Ligation in Heme Systems:Thiolate Adducts of the Myoglobin H93G Cavity Mutant
salicylic alcohols hydrogen bonds quantum chemistry
2016/5/23
Recently, heme protein cavity mutants have been engineered in which the proximal coordinating amino acid has been replaced by a smaller, noncoordinating residue leaving a cavity that can be filled by ...
Protein Relaxation Dynamics in Human Myoglobin
Protein Relaxation Dynamics Human Myoglobin
2016/5/23
Transient absorption spectra in the Soret region have been measured following the photolysis of human MbCO in 75%(w/w) glycerol:water at 250, 270, and 290 K. The peak of the transient difference spect...
Effects of Buried Ionizable Amino Acids on the Reduction Potential of Recombinant Myoglobin
Buried Ionizable Amino Acids Reduction Potential Recombinant Myoglobin
2016/5/20
The temperature dependences of the reduction potentials (E degrees') of wild-type human myoglobin (Mb) and three site-directed mutants have been measured by the use of thin-layer spectroelectrochemist...
The Effect of Heating Temperature on the Prooxidant and Hydroperoxide Decomposition Activity of Myoglobin
myoglobin heating prooxidant activity
2009/7/8
Solutions of myoglobin from the heart of a horse were heated at various temperatures to assess the effect of heating temperature on the prooxidant and hydroperoxide decomposition activity of myoglobin...
Antioxidative Effects of Phenolic Acids on Lipid Peroxidation Induced by H2O2 in the Presence of Myoglobin
caffeic acid ferulic acid hydrogen peroxide
2009/6/18
Antioxidant effects of the phenolic acids, caffeic acid, p-coumaric acid, and ferulic acid, were investigated by monitoring O2 consumption in the linoleic acid micelles in the presence of H2O2 and met...
Formation of Zinc Protoporphyrin IX from Myoglobin in Porcine Heart Extract
Zn-protoporphyrin IX myoglobin porcine heart
2009/5/31
The formation of zinc protoporphyrin IX (ZPP) in porcine heart extract was investigated by visible absorption and fluorescent spectral analysis. Characteristic absorption peaks of ZPP were observed at...
