De novo peptide sequencing via manual interpretation of MS/MS spectra. Author information: (1)Millennium Pharmaceuticals, Cambridge, Massachusetts, USA. Methods are also provided for verification of the results of the de novo analysis through chemical modification and limited manual Edman degradation of the peptide.
20 Dec 2017 Request (PDF) | De Novo Peptide Sequ | Databases of complete genome sequences are rapidly appearing, and a recent trend in interpretation of peptide MS/MS spectra is database matching. A caveat of database matching is that it can only be successful if the database being searched contains the
11 Jul 2007 Advice on interpreting tandem mass spectra of peptides. A tandem, or MS/MS, spectrum is made by selecting a narrow mass range from a MALDI spectrum, bombarding the ions into argon atoms so that they fragment, and separating the . We will go through how this might be analysed manually.
13 Jan 2010 Join Brian Searle on an illustrated tour about interpreting MS/MS peptide spectra. On this tour you will first see how you can relate mass spectra to peptides.
1. Compute the protonated molecular weight for the peptide – generally from the observed doubly-charged precursor ion ([M+H]+ = ion m/z * charge – (charge-1). This will not work for an ion trap mass spectrometer, since the low mass region is generally excluded. Immunium ion masses range from m/z 30 – 159.
16 Nov 2010 De Novo Peptide Sequencing via Manual. Interpretation of MS/MS Spectra. In a matter of a few seconds, a mass spectrometer is capable of ionizing a mixture of peptides with different sequences and measuring their respective mass-to-charge ratios. Under low-energy collisions in a tandem mass
18 Jul 2005 A simple tutorial on electrospray mass spectrometry spectra interpretation.
Therefore, the search algorithm checks the quality of the MS/MS spectra by assigning the fragments to a known sequence. Not all search algorithms take into . It is very difficult, nearly impossible, to manually interpret an MS/MS spectrum and arrive at a result that is unique and correct result. Eg., if you manage to find that
The peaks will appear to differ by the approximate mass of an amino acid residue as shown below. Figure 1. This is an MS/MS spectrum of the tryptic peptide GLSDGEWQQVLNVWGK. This data was collected on an ion trap mass spectrometer. This spectrum will be the subject of our first unblinded de novo sequencing
Given the success of database search programs at identifying proteins (Clauser et al., 1999; Eng et al., 1994; Fenyo et al., 1998; Mann and Wilm, 1994; Perkins et al., 1999), one could reasonably question the importance of knowing how to manually interpret tandem mass spectra (MS/MS) of peptides.
