Resumen:
The selectivity of MnIII/II porphyrinates towards nitroxyl or nitric oxide donors provides a convenient starting point for the development of new materials for the speciation of these nitrogen-containing redox relatives. In the present report, we describe the insertion of MnIII protoporphyrinate IX in apomyoglobin and its chemical behavior towards HNO or NO donors, either under anaerobic or aerobic conditions. For comparison and discussion, the MnIII porphyrinate, devoid of the protein matrix, was studied in parallel.
