## Abstract Phosphorylation of proteins is an important post‐translational protein modification in cellular response to environmental change and occurs in both prokaryotes and eukaryotes. Identification of the amino acid on individual proteins that become phosphorylated in response to extracellular
## Incident ion energy Ei and collision gas pressure have been adjusted so as to obtain a satisfactory tandem mass spectrum of the m/z 1882 ion formed from valine-gramicidin A (relative molecular mass 1881). Translational energy losses AE have been determined (at Ei = 14.8 keV) from the precise po
