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 ...

Phycocyanobilin (PCB) is a natural blue chromophore found in cyanobacteria. PCB is expected to be applied as a food colorant and to pharmaceuticals with anti-inflammatory and antioxidant properties.

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 ...

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 ...

A chromophore is a group of atoms and electrons (or moiety) i.e. part of organic molecules responsible for its colour. A chromophore is a group of atoms and electrons (or moiety) i.e. part of organic ...
