Recordings of electronic currents from plant cytochromes

Cytochromes b561 are a family of proteins responsible for the transfer of electrons from a donor (ascorbate) to an acceptor placed on opposite sides of the cell membrane. They are also present in plants where they are involved in many redox processes: from the control of reactive oxygen species (ROS) to ascorbate regeneration. Previously, our group detected, for the first time, electronic currents of animal and plant b561 cytochromes expressed in Xenopus oocytes. Currently, my activity has focused on the characterization of a cytochrome b561, whose structure is known, present in the vacuolar membrane of the model plant Arabidopsis thaliana.
