Abstract

Positive and negative FAB-MS as well as B/E linked scan are used for the determination of the amino acid sequence of mastoparan B, a toxin isolated from the hornet (Vespa Basalis) venom. It is demonstrated that useful sequence information can be deduced from the FAB-MS and B/E-CAD spectra. In conjunction with the information from Edman degradation method, complete deduction of the entire amino acid sequence is presented.
