Tokyo, Japan – Scientists from Tokyo Metropolitan University have identified a new photoreceptor in cyanobacteria with a modification in part of its structure which makes it sensitive to green/teal light. The photoreceptor belongs in a family usually sensitive to red/green light in the environment. They identified the parts of its amino acid structure responsible for this behavior; editing them helped restore sensitivity to red and green light, a remarkable example of molecular “plasticity” in action.
The title sheds a serious pun.
