Application

O-(2-Nitrobenzyl)-L-tyrosine hydrochloride (NBY) is a tyrosine derivative with an o-nitrobenzyl photocage that can be cleaved with 365 nm irradiation. NBY has been genetically encoded into multiple proteins, providing an ″on switch″ for regulation. Photocaged amino acids such as these are also useful in the synthesis of photocleavable chemical tools for spatial and temporal control over released molecules in biological applications.

In vivo incorporation of isotopically labeled unnatural amino acids into large proteins drastically reduces the complexity of nuclear magnetic resonance (NMR) spectra. Incorporation is accomplished by coexpressing an orthogonal tRNA/aminoacyl-tRNA synthetase pair specific for the unnatural amino acid added to

We developed two tightly regulated, light-activated Cre recombinase enzymes through site-specific incorporation of two genetically-encoded photocaged amino acids in human cells. Excellent optical off to on switching of DNA recombination was achieved. Furthermore, we demonstrated precise spatial control of Cre
