Russian scientists open structure of the light-absorbing protein

Life on earth depends on solar energy. Scientists from all over the world are trying to understand the mechanisms of trapping and absorption of solar energy. Only recently a study in busine answer to this question. Scientists from Russia, together with colleagues from Germany and France discovered the principle of operation of the light-absorbing protein proteorhodopsin, which is found in some bacteria.

Protein in its structure similar to the rhodopsin - the substance responsible for the perception of light in both animals and humans. Russian scientists conducted a study of this protein, highlight it using the technology of the Institute of soil Sciences. Was deciphered genotype of bacteria that are found in Yakutia, in the permafrost zone. Scientists made the gene responsible for the perception and absorption of light, to work in the bacteria Escherichia coli group, producing protein proteorhodopsin. Work is currently under way to study photocycle of this protein.

Obtained further experience will be useful in such areas as optogenetics. Perhaps it will create new methods of control over life cycles of living organisms. But the deciphering of the structure of a protein is a big step forward. Scientists have tried to understand his device with the 70-ies.
