Journal ArticleDOI
Dimeric and tetrameric hemoglobins from the mollusc Scapharca inaequivalvis: Structural and functional properties
TL;DR: The optical and circular dichroism spectra show that the heme environment in HbI and HbII resembles that of vertebrate hemoglobins, although distinctive features are present in the deoxygenated derivative.
Journal ArticleDOI
Thermal stability of horse spleen apoferritin and human recombinant H apoferritin.
Simonetta Stefanini,Stefano Cavallo,Changqing Wang,Paola Tataseo,Paola Vecchini,Anna Giartosio,Emilia Chiancone +6 more
TL;DR: The results indicate that the stabilization of thepolymeric structure arises mainly from interactions between dimers, in accordance with the crystallographic evidence that the dimers are the building blocks of the polymeric molecule.
Journal ArticleDOI
Purification and Characterization of 3,4-Dihydroxyphenylalanine Decarboxylase from Pig Kidney
TL;DR: A procedure for 3,4-dihydroxyphenylalanine decarboxylase from pig kidney purification is described in detail and results are consistent with the existence of at least four coenzyme-apoenzyme complexes, three of them active.
Journal ArticleDOI
Studies on erythrocruorin. I. Physicochemical properties of earthworm erythrocruorin.
TL;DR: Erythrocruorin has been purified by preparative ultracentrifugation from the blood of Lumbricus and contains 144 hemes arranged in a subunit structure similar to that of other erythrocromorins and of Spirographis chlorocrun.
Journal ArticleDOI
Free energy of burying hydrophobic residues in the interface between protein subunits
TL;DR: An experimental estimate of the free energy change associated with variations at the interface between protein subunits, a subject that has raised considerable interest since the concept of accessible surface area was introduced by Lee and Richards is obtained.
