WebIt has been shown that the phosphorous–nitrogen bond was hydrolyzed very fast under acidic conditions and at elevated temperatures. 23 For example, the half-life time of pLys is approx. 2.5 h at room temperature and pH 3.5 or below and even less than 1 h at 60 °C and neutral pH. 23 Therefore, a fine-tuned assay with less delay between each step … WebPhosphoramidate bonds have a phosphorus-nitrogen (P-N) bond. The ability of phosphatases to cleave such phosphoramidate bonds is not well studied. The research herein involved a side-by-side comparison of the abilities of the known phosphatases to cleave the P-O bond of pNPP and the P-N bonds of N-phenyl phosphoramidate and …

WebOct 21, 2005 · Molecular geometries showed no major distortions, and bond lengths and angles oscillated about their equilibrium values to an extent that is also expected for the unphosphorylated amino acids. For the phosphate groups of phospho-amino-acid residues, free rotation around the O-phosphomonoester or phosphoramidate bond would be … WebJan 1, 2024 · Thus, a high free energy of hydrolysis makes pHis relatively unstable and the phosphoramidate bond rapidly hydrolyzes at low pH or when exposed to significant heat. However, the routine O-phosphorylation enrichment methods require strong acid incubation condition (pH < 2.0) which causes phosphoramidate bond hydrolysis [26].
