Abstract

The Proteomics of methanococcus jannaschii and saccharomyces cerevisiae were studied using a quadrupole FT-ICR-MS. It was found that the top down approach fragments intact proteins within the mass spectrometer, which allowed more sequence coverage. It was shown that the micro-electrosprayed ion was desolvated and transported for accumulation either by placing the quadrupole in rf-only or mass filtered by quadrupole. Analysis shows that post transcription processing events increased proteome complexity which ultimately increased the database complexity for larger proteins in higher order organisms.
