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. ...
Structural flexibility of the heme cavity in the cold-adapted truncated hemoglobin from the Antarctic marine bacterium Pseudoalteromonas haloplanktis TAC125
(Wiley Blackwell Publishing, Inc, 2015-08)
Truncated hemoglobins build one of the three branches of the globin protein superfamily. They display a characteristic two‐on‐two α‐helical sandwich fold and are clustered into three groups (I, II and III) based on distinct ...
