The structure of tridecaptin A (studies on antibiotics from the genus Bacillus. XXIV).

On examining the structure of the antibiotic tridecaptin A, the constituent amino acids were determined to be: 2,4-diaminobutyric acid(2D, 1L), Ser(1D, 1L), Glu(1L), Gly(1), Ala(1L), Val(1D, 1L), aIle(1D), Phe(1L) and Trp(1D). The constituent fatty acid was identified as beta-hydroxy anteisononanoic acid by gas chromatography and mass spectrometry. Cleavage reaction with N-bromosuccinimide, sequential analysis by EDMAN degradation, partial acid hydrolysis and some additional evidences clarified the structure of tridecaptin A.
