Multinuclear NMR Studies of Hemoproteins and Their Model Compounds
… to study the active site structure of various hemoproteins, and the nature of the iron-oxygen bond in oxyhemoglobin. The first iron-57 NMR spectra of a metalloprotein, carbonmonoxymyoglobin, has been obtained, yielding the isotropic chemical shift, the anisotropy of the chemical shielding …

The Utilization of Metalloporphyrins as Mechanistic Probes of the Active Site of Heme Proteins
… site for dioxygen in O$\sb2$ transport/storage hemoproteins. In the latter, one observes a range of 10$\sp5$ in O$\sb2$ affinities among heme proteins, discrimination in binding O$\sb2$ vs. CO, and cooperative ligand binding observed in hemoglobin.

Partial structural characterization of the cytoplasmic hemoglobin of Nostoc commune UTEX 584 expressed in Escherichia coli
… a similar heme environment in these two hemoproteins. Far-UV CD of cyanoglobin revealed alphahelical character comparable to that of sperm whale myoglobin and leghemoglobin α. Cyanoglobin is the first monomeric hemoglobin detected in a prokaryote, raising questions concerning a possible …

From physiology to pixels: Resource allocation tradeoffs and noninvasive technologies for studying marine mammals
… females transferred iron, a key component of hemoproteins that support large oxygen stores and aerobic performance in diving mammals. My findings demonstrated that adult females with greater iron reserves raised pups that also had larger iron stores by the time they are weaned, while iron …

ΑΝΑΛΥΣΗ ΤΩΝ ΑΛΛΗΛΕΠΙΔΡΑΣΕΩΝ ΑΝΘΡΑΚΥΚΛΙΝΩΝ-ΣΙΔΗΡΟΠΟΡΦΥΡΙΝΩΝ ΣΤΟ ΑΙΜΟΠΟΙΗΤΙΚΟ ΣΥΣΤΗΜΑ
… LED US TO PROPOSE THAT ADR MAY INTERACT WITH HEMOPROTEINS OF VITAL IMPORTANCE TO BOTH DIVIDING AND NON-DIVINDING CELLS. IN THECONTEXT OF THIS RATIONALE, WE USED [3H(G)]-DAU AND OBSERVED THAT IT INTERACTS SELECTIVELY WITH MITOCHONDRIAL COMPONENTS (OF LARGE M.W.) BY FORMING RELATIVELYSTABLE …

Design, synthesis, and characterization of porphyrin derivatives for biological applications
… The importance of the construction of artificial hemoproteins to understand the cytochromes activity is also discussed. Various synthetic routes and strategies to obtain the symmetric porphyrin are reported in detail.

Characterization of the nifUHD cluster and a new myoglobin-like gene from Nostoc commune UTEX 584
… CO resulted in spectral shifts characteristic of hemoproteins that bind oxygen. While some of the spectral characteristics are unique to the protein, in general the spectra were more like those of globins than cytochromes. Based on these characteristics and the sequence similarity to the P. …

Molecular Mechanisms Underlying Aerobic Respiration and Heme Regulation in Yeast
Heme is an important signaling molecule with diverse functions in living organisms ranging from regulating gene transcription to circadian rhythm. In yeast, heme serves as a secondary messenger of oxygen, as heme synthesis depends on the intracellular levels of oxygen. Yeast and higher eukaryotes …
