Abstract
Advances in acetylated protein-protein/DNA interactions depend on the development of a novel NMR (nuclear magnetic resonance) probe to study the conformational changes of acetylated proteins. However, the method for detecting the acetylated protein conformation is underdeveloped. Herein, an acetyllysine mimic has been exploited for detecting the conformational changes of acetylated p53-protein/DNA interactions by genetic code expansion and 19F NMR. This 19F NMR probe shows high structural similarity to acetyllysine and could not be deacetylated by sirtuin deacetylase in vitro/vivo. Moreover, acetylation of p53 K164 is reported to be deacetylated by SIRT2 for the first time.

Abstract
Genetically encoded magnetic resonance imaging (MRI) contrast agents enable non-invasive detection of specific biomarkers in vivo. Here, we employed the hyper-CEST 129Xe NMR technique to quantify maltose (32 nM to 1 mM) through its modulation of conformational...

Abstract
The amino acids 4-(tert-butyl)phenylalanine (Tbf) and 4-(trimethylsilyl)phenylalanine (TMSf), as well as a partially deuterated version of Tbf (dTbf), were chemically synthesized and site-specifically incorporated into different proteins, using an amber stop codon, suppressor tRNA and the broadband aminoacyl-tRNA synthetase originally evolved for the incorporation of p-cyano-phenylalanine. The 1H-NMR signals of...
