Spin and electron distributions in heme-cyanide models and hemeproteins
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1985Proton NMR spectra of low-spin Fe(III) cyanoprotoheme as prosthetic group in a number of proteins are presented. The diagonally positioned 1-, 5- and 3-, 8-methyl groups obey shifts proportional to the Fe(III)/(II) reduction potential Em7, which indicates a pseudo-contact interaction.

Azanone (HNO) interaction with Hemeproteins and metalloporphyrins
2012Abstract Azanone (HNO), also called nitroxyl, is a highly reactive compound, with interesting yet poorly understood biological properties. Like its closely related sibling NO, its main biological targets are heme proteins, although significant differences in their reactivity and pharmacological effects are observed.

Optical rotatory dispersion of a respiratory hemeprotein of Chrinomus thummi
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1968Abstract The spatial structure of an O 2 -binding hemeprotein obtained from Chironomus thummi is compared with that of sperm whale myoglobin by means of rotatory dispersion. The optical rotation at the 233-mμ minimum of the ultraviolet Cotton effect is only 70% of the value obtained for myoglobin.

Protein Fluctuations and Hemeprotein Affinity for Ligand
1986Binding processes in hemeproteins involve the iron atom and the protein properties: structural and dynamics. Crystallographic data of Perutz have given an appreciate popularity to a correlation between the displacement of the iron out of the porphyrin plane and the affinity of the hemeprotein for ligand.

Vibrational Circular Dichroism of Ligand Vibrations in Hemeprotein
1995The distal amino acid residues in myoglobin (Mb) and hemoglobin (Hb) are elaborately designed to control the chemical reactions of ligands to the heme iron. Many techniques have been applied to elucidate the reaction mechanism of ligand binding in heme pockets.
