Molecular plasticity of cyanobacteriochromes. 

(left) Scientists have discovered a new CBCR binding PVB (pink) in a family of photoreceptors usually binding PCB (blue). (right) The new CBCR binding PVB (pink) can switch between two differently absorbing states (two curves), giving it sensitivity to green and teal light (top). When three amino acid residues are modified in the CBCR, PVB is isomerized to PCB (blue), changing the nature of the absorbing states completely.
