The printed version of the journal Nature published an article where the research group Molecular Genetics at the University of Murcia (UMU), led by Professor Montserrat Elias describes the operation of a new type of photoreceptor proteins using vitamin B12 as light sensor molecule.
The article provides a new tool for the design of new artificial protein capable of carrying out certain functions in response to light.
With this research has managed to capture "snapshots" of a new photoreceptor not found before in nature.
"Only six families were known photoreceptors, therefore, the type of photoreceptor protein discovered by us, founder of the CARH family, adds to the existing list scarce," says Montserrat Elijah.
In research Maria Carmen Polanco and Juan Manuel Ortiz involved, the UMU group;
Jesus Fernandez Padmanabhan and Subramanian, the Higher Council for Scientific Research (CSIC) and Marco Jost, Percival Yang-Ting Chen, Kang Gyunghoon and Catherine L. Drennan, Massachusetts Institute of Technology (MIT).
The group of Molecular Genetics at the University of Murcia was the one who, in 2002, found that vitamin B12 molecule could be used as a light sensor.
Last August, the same group, in collaboration with researchers from the University of Manchester (UK), published a paper in Nature Communications, which demonstrated that the use of vitamin B12 as a light sensor molecule occurs by a photochemical mechanism unprecedented.
