MRMPath and MRMutation, Facilitating Discovery of Mass Transitions for Proteotypic Peptides in Biological Pathways Using a Bioinformatics Approach

Figure 3

A screen capture of MRMPath results (truncated) shows the peptides for a chosen protein (isocitrate dehydrogenase) from the TCA cycle pathway. The peptides are a result of a tryptic digest, the precursor ion values and the b- and y-ions whose masses are greater than that of the precursor ion identified. The link towards the top of the page allows users to download the processing result to an Excel spreadsheet. The buttons that allow BLAST searching of individual peptides as well all peptides from the chosen protein are also illustrated in the figure.
