Analysis of the activation mechanism of Pseudomonas stutzeri cytochrome c perox...
Sousa, P. M. Paes de; Rodrigues, D.; Timóteo, C. G.; Gonçalves, M. L. Simões; Pettigrew, G. W.; Moura, Isabel; Moura, José J. G.J Biol Inorg Chem (2011) 16:881–888 DOI 10.1007/s00775-011-0785-8
Benefits of membrane electrodes in the electrochemistry of metalloproteins: med...
Sousa, P. M. Paes de; Pauleta, Sofia R.; Rodrigues, D.; Gonçalves, M. L. Simões; Pettigrew, G. W.; Moura, Isabel; Moura, José J. G.J Biol Inorg Chem. 2008 Jun;13(5):779-87. doi: 10.1007/s00775-008-0365-8 ; A comparative study of direct and mediated electrochemistry of metalloproteins in bulk and membrane-entrapped solutions is presented. This work reports the first electrochemical study of the electron transfer between a bacterial cytochrome c peroxidase and horse heart cytochrome c. The mediated catalysis of the peroxidase was analysed b...
Mediated catalysis of Paracoccus pantotrophus cytochrome c peroxidase by P. pan...
Sousa, P. M. Paes de; Pauleta, Sofia R.; Gonçalves, M. L. Simões; Pettigrew, Graham W.; Moura, Isabel; Moura, José J. G.J Biol Inorg Chem (2007) 12:691–698 DOI 10.1007/s00775-007-0219-9 ; This work reports the direct electrochemistry of Paracoccus pantotrophus pseudoazurin and the mediated catalysis of cytochrome c peroxidase from the same organism. The voltammetric behaviour was examined at a gold membrane electrode, and the studies were performed in the presence of calcium to enable the peroxidase activation. A formal reducti...
Electrochemical studies on small electron transfer proteins using membrane elec...
Moura, José J. G.; Santos, M.M. Correia dos; Sousa, P.M. Paes de; Gonçalves, M.L. Simões; Krippahl, L.; Lojou, É.; Bianco, P.Journal of Electroanalytical Chemistry 541 (2003) 153-162 ; Membrane electrodes (ME) were constructed using gold, glassy carbon and pyrolytic graphite supports and a dialysis membrane, and used to study the electrochemical behavior of small size electron transfer proteins: monohemic cytochrome c522 from Pseudomonas nautica and cytochrome c533 as well as rubredoxin from Desulfovibrio vulgaris . Different electr...
