title: Mass spectrometric peptide sequencing: cyclochlorotine.
abstract: A potent toxin isolated from Penicillium islandicum Sopp was found to have the composition C24H31N5O7Cl2. Mass spectrometric investigation of a partial acid hydrolyzate showed that it has the structure of cyclochlorotine. The mass spectral characteristics of polyamino alcohol-related derivatives of peptides containing beta-phenylalanine, alpha-amino butyric acid and dichloroproline were determined in the course of this work.
