Sequential product-ion spectra (MS3) with array detection and reaction-intermediate scanning of a cyclopeptide on a five-sector mass spectrometer.
A new strategy, based on sequential product-ion spectra (MS2 and MS3) and reaction-intermediate scanning (MS3), provides a rapid and unambiguous sequence determination of E-destruxin, a cyclodepsipeptidic toxin from Metarrhizium anisopliae fungus.
