WebAn important advance in the study of the impact of lysine acetylation on cytoskeleton regulation was the development of several chemical biological tools, including GCE, to genetically encode acetyl-lysine and analogues thereof, photoactivatable crosslinkers, fluorescent, and photocaged amino acids (Figure 5D). WebOct 1, 2024 · For this purpose, a variety of photocaged UAAs (photo-UAAs) has been designed, including lysine [37, 38], cysteine [39, 40], and tyrosine [41, 42, 43] derivates (Figure 3 a). Typically, such UAAs replace functionally critical amino acids within the active site of the target protein rendering it inactive.
