mMass as a software tool for the annotation of cyclic peptide tandem mass spectra. [PDF]

PLoS ONE, 2012
Natural or synthetic cyclic peptides often possess pronounced bioactivity. Their mass spectrometric characterization is difficult due to the predominant occurrence of non-proteinogenic monomers and the complex fragmentation patterns observed. Even though
