Conformational changes associated to sensing mechanisms of heme-based protein sensors are a key molecular event that seems to modulate not only the protein activity but also the potential of the FeIII/II redox couple of the heme domain. In this work, midpoint potentials (Em) assigned to the FeIII/II redox couple of the heme domain of FixL from Rhizobium(More)
Coordination compounds of copper have been invoked as major actors in processes involving the reduction of molecular oxygen, mostly with the generation of radical species the assignment for which has, so far, not been fully addressed. In the present work, we have carried out studies in solution and on surfaces to gain insights into the nature of the radical(More)
