phage-display based approach
Engineering MethodThis phage-display based approach was used to generate small monomeric binders that selectively recognize green-absorbing, red-absorbing, and far-red-absorbing photostates of the cyanobacteriochrome Am1_c0023g2 under specified chromophore conditions. The resulting binders enabled multicolor light-dependent control of protein-protein interactions in vitro and transcriptional control in yeast in vivo.
