Application

o-Nitropiperonyl-O-tyrosine (NPY) is a photo-responsive unnatural amino acid (UAA) for spatiotemporal control of biological molecules or processes as reported by Kneuttinger et al. Irradiation with UV light decages the Tyr amino acid, freeing the residue or protein for biological activity. Tools such as NPY will find wide utility in light regulation of activity, allostery, and enzyme pathways.

Product can be used with our line of photoreactors: Including Penn PhD (Z744035) & SynLED 2.0 (Z744080)

Imidazole glycerol phosphate synthase (ImGPS) is an allosteric bienzyme complex in which substrate binding to the synthase subunit HisF stimulates the glutaminase subunit HisH. To control this stimulation with light, we have incorporated the photo-responsive unnatural amino acids phenylalanine-4'-azobenzene (AzoF)
