Over the past decade, photoswitchable molecules have been emerging as attractive tools for investigating biological processes with spatiotemporal resolution in a minimally invasive fashion. Photoswitches built on light-sensitive proteins or domains have significantly advanced neuronal and cellular studies. To install photosensitivity to general proteins and to enable high specificity for modulation, photoswitchable click amino acids (PSCaas) based on azobenzene have been developed and recently genetically incorporated into proteins via the expansion of the genetic code. PSCaas allow targeting selected sites in a protein for high specificity and are generally applicable to various proteins. In addition, PSCaas contain a click functional group, which selectively reacts with an appropriately positioned cysteine forming a photocontrollable bridge on the protein in situ. The photocontrollable bridge enables reversible modulation of the secondary structure of the spanned region and thus the function of the protein. In this chapter we describe the design and genetic encoding of PSCaa. Protocols are presented for incorporating PSCaa into a model protein calmodulin to build the bridge followed by photocontrol of calmodulin's conformation and binding function.
