WebAbstract. The mechanisms of magnetoreception have been proposed as the magnetite-based, the chemical radical-pair and biocompass model, in which magnetite particles, … WebFigure 1 Right: Cryptochrome internally binds the FAD cofactor and contains a three-tryptophan photoreduction pathway conserved from photolyase, consisting of Trp400, Trp377, and Trp324, with Trp400 nearest the FAD and Trp324 closest to the protein surface. After the FAD cofactor absorbs a photon, bringing it into an excited state, it is protonated …

WebApr 30, 1999 · Cryptochromes are blue, ultraviolet-A photoreceptors. They were first characterized for Arabidopsis and are also found in ferns and algae; they appear to be ubiquitous in the plant kingdom. They are flavoproteins similar in sequence to photolyases, their presumptive evolutionary ancestors.
WebJun 2, 2000 · Raman spectra of hexagonal close-packed iron (ɛ-Fe) have been measured from 15 to 152 gigapascals by using diamond-anvil cells with ultrapure synthetic diamond anvils.The results give a Grüneisen parameter γ 0 = 1.68 (±0.20) and q = 0.7 (±0.5). Phenomenological modeling shows that the Raman-active mode can be approximately … 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.
