ESI-MS spectrum.Agustina, García
We show that CFM can be used in both a MS/MS spectrum prediction task (ie, predicting the mass spectrum from a chemical structure), and in a putative metabolite identification task (ranking possible structures for a target MS/MS spectrum). In the MS/MS spectrum prediction task, CFM shows ...

The lower figure is the mass spectrum of a peptide as it was first sent to us. None of the ions corresponded to the supposed MW of the peptide. The material was a “pure” HPLC peak. After modification of the isolation procedure, the mass spectrum of some PURE peptide was obtained.
The peptide/protein mass is determined by deconvolution of the ESI-MS spectrum, and the resolution can be better than 1:10,000 with the instruments currently available. Accurate mass measurement, coupled with sufficient resolution, makes it possible to greatly restrict the enormous number of ...

We also observed the phosphorylation of PPP1R12B at the pThr646 proximal site, Ser645, although these 2 phospho sites were not distinguishable based on the MS/MS spectrum, and whether they behave similarly in the regulation of PPP1R12B is unclear at present. Mutation of Thr646 or Ser645 ...
