Webcryptochrome is in some way optimal for detecting the mag- netic field of the earth and that the magnetoreception function cannot be easily taken over by other molecules. WebJan 1, 2010 · Firstly, cryptochromes are activated via an intraprotein electron transfer mechanism that generates radical pairs comprising flavin and one of several tryptophan and/or tyrosine residues forming a chain of electron transfer to the surface of the protein. 10 – 12 Radical formation in this way activates the protein and induces biological activity.
WebDec 19, 2024 · In fact, it has become increasingly evident that cryptochromes, which mainly absorb in the blue light region, also act as key regulators of a range of plant stress responses, such as drought, salinity, heat, and high radiation. However, this information is rarely evidenced in photomorphogenetic studies. Therefore, the scope of the present ... Webas iron oxides. In the proper geometry, iron oxide clusters can behave like a compass needle and magnetic bacteria use such a compass needle mechanism to find up and down. An alternative possibility is to use short-lived, specialized photochemical reac-tions, for which thermal noise does not have time to effectively mask effects of magnetic fields.
