Researchers from the Catalonian Institute of Bioengineering (Instituto de Bioingeniería de Cataluña) and the Seville Chemical Research Institute (Instituto de Investigaciones Químicas de Sevilla) have described a new method for the transmission of electrons between proteins that refutes the evidence from experiments until now. This process, involved in the generation of energy in both animal and plant cells, will permit better understanding of the behaviour of proteins in the cells, as well as giving a deeper understanding of the energy dysfunctions that cause diseases.

The production of energy inside living cells is fundamental to correct metabolic function. For that reason, specialised organelles exist that are called chloroplasts in plant cells and mitochondria in animal cells. In these, plants transform the energy of the sun into useful chemical energy – in a process known as photosynthesis – and animals combust food with oxygen from the air to use the energy released during breathing.

Transfer - Electrons - Proteins - Contact - Formation

Both processes involve the transfer of electrons between specialised proteins. For that, it is necessary to have physical contact between them and the consequent formation of a transitory intermediate state to establish the route...
