The results have been correlated with the decrease in affinity of the various modified hemes for globin and suggest that the vinyl groups of the heme play an important role in determining the conformation of the hemoglobin molecule.doi:10.1016/0926-6585(64)90009-3E. Antonini...
Hemoglobin structure in a detailed, interactive and illustrated tutorial with colorful and simple animations about its states (relaxed & tensed).
which an iron atom is attached. It is the iron atom that binds oxygen as the blood travels between thelungsand the tissues. There are four iron atoms in each molecule of hemoglobin, which accordingly can bind four molecules of oxygen. Globin consists of two linked pairs of polypeptide chains...
The chapter presents the studies that were made on the hemochrome-forming chemical groups of some hemoproteins after the proteins had been artificially unfolded. The heme–heme interaction, the Bohr Effect, and the affinity for ethyl isocyanide of hemoglobin were independent of each other and were...
It is also a type of metalloprotein because of the presence of metallic iron in its structure. The molecule of hemoglobin is also responsible for transporting the carbon dioxide molecules in the blood. The term hemo is used for blood in the greek terminology; therefore the term hemoglobin is ...
George and Pauling to the conclusion that there is steric hindrance between the alkyl groups of the isocyanides and a part of the globin in the hemoglobin molecule. Inasmuch as it is known that the heme group is attached to globin by way of an imidazole ring of a histidine side chain of...
Primary structure of the human heparan sulfate proteoglycan from basement membrane (HSPG2/perlecan). A chimeric molecule with multiple domains homologous t... We have determined the complete nucleotide and deduced amino acid sequence of the major protein core of the human heparan sulfate proteoglycan...
ADH EM density effectively demonstrates the utility of conventional SPA methods for structure-based drug design and other small-molecule research involving similarly sized specimens. Two states of methemoglobin at ~2.8 Å and ~3.2 Å resolution ...
