The sequence of changes that light triggers in a bacterial photoreceptor starts with its protein scaffolding rather than the light-absorbing chromophore, an all-RIKEN team has shown. This finding goes ...

Proteins from the green fluorescent protein (GFP) family are essential markers in the world of molecular and cellular biology because they help to visualize cellular components and processes. They ...

The membrane protein bacteriorhodopsin is a proton pump, in which proton transport is initiated by the light-induced isomerization of the chromophore retinal. The molecular quantum states involved in ...

A normally undesirable property of chromophores is used in the creation of a genetically encoded tag for correlated light and electron microscopy. Most jobs are best filled by people who are ...

Fluorescence usually entails the conversion of light at shorter wavelengths to light at longer wavelengths. Scientists have now discovered a chromophore system that goes the other way around. When ...
