Cryptochromes are flavoprotein photoreceptors first identified in Arabidopsis thaliana, where
they play key roles in growth and development. Subsequently identified in prokaryotes …

Nowadays, time-resolved spectroscopy data can be routinely and accurately collected in UV–
vis femtosecond transient absorption spectroscopy. However, the data analysis strategy and …

DNA photolyase uses visible light and a fully reduced flavin cofactor FADH− to repair major
UV-induced lesions in DNA, the cyclobutane pyrimidine dimers (CPDs). Electron transfer …

Cryptochromes are flavin-based photoreceptors occurring throughout the biological
kingdom, which regulate growth and development in plants and are involved in the …

The remarkable phenomenon of magnetoreception in migratory birds and other organisms
has fascinated biologists for decades. Much evidence has accumulated to suggest that birds …

A 4th electron transferring tryptophan in animal cryptochromes and (6-4) photolyases is
discovered and functionally analyzed by transient absorption. It yields a much longer-lived …

Cryptochromes (Crys) are blue light receptors believed to have evolved from the DNA
photolyase protein family, implying that light control and light protection share a common …

Flavins are highly versatile redox-active and colored cofactors in a large variety of proteins.
These do include photoenzymes and photoreceptors, although the vast majority performs …

The magnetic compass of migratory birds is thought to rely on a radical pair reaction inside
the blue-light photoreceptor protein cryptochrome. The sensitivity of such a sensor to weak …

The first stage in biological signaling is based on changes in the functional state of a
receptor protein triggered by interaction of the receptor with its ligand (s). The light-triggered …
