| Resumen en inglés | UV-Vis and fluorescence spectroscopic studies of native and reconstituted d monomers from Glossoscolex paulistus were performed in alkaline pH. In addition to the presence of aquomet and hemichrome hexacoordinated species, a pentacoordinated species occurs. This latter species, which presents an imidazolate group of axial histidine as fifth ligand, is identified by the blue-shifted low-intensity Soret band and LMCT band. The pentacoordinated species must occur due to partial polypeptide unfolding |
