Studies on Metabolites of Mycoparasitic Fungi. V. Ion-Spary Ionization Mass Spectrometric Analysis of Trichokonin-II, a Peptaibol Mixture Obtained from the Culture Broth of Trichoderma koningii

Abstract

The sequence of a peptide, trichokonin-II (TK-II), obtained from the culture broth of Trichoderma koningii OUDEMANS, was examined by ion-spray ionization mass spectrometry (ISI-MS), including the collision-induced dissociation (CID) technique. TK-II was concluded to be a mixture of three peptaibols, TK-IIa, TK-IIB, and TK-IIc.
