Hydration-dependent conformational states of hemoglobin. Equilibrium and kinetic behavior
(1990-07-27)
The equilibrium and kinetics of methemoglobin conversion to hemichrome induced by dehydration were investigated by visible absorption spectroscopy. Below about 0.20 g water per g hemoglobin only hemichrome was present in ...

Ferric species equilibrium of the giant extracellular hemoglobin of Glossoscolex paulistus in alkaline medium: HALS hemichrome as a precursor of pentacoordinate species
(ElsevierAmsterdam, 2008-03)
The present work is focused on the complex ferric heme species equilibrium of the giant extracellular hemoglobin from Glossoscolex paulistus (HbGp) in alkaline medium. EPR, UV-vis and CD spectroscopies were used in order ...

Ferric species of the giant extracellular hemoglobin of Glossoscolex paulistus as function of pH: an EPR study on the irreversibility of the heme transitions
(ElsevierNew York, 2008-07)
The present article is focused on the transitions of ferric heme species of the giant extracellular hemoglobin of Glossoscolex paulistus (HbGp) induced by successive alterations in pH, involving alkaline and acid mediums. ...

On the stability of the extracellular hemoglobin of Glossoscolex paulistus, in two iron oxidation states, in the presence of urea
(ELSEVIER SCIENCE INCNEW YORK, 2012)
The stability of the Glossoscolex paulistus hemoglobin (HbGp), in two iron oxidation states (and three forms), as monitored by optical absorption, fluorescence emission and circular dichroism (CD) spectroscopies, in the ...
