title: The structure of histargin.
abstract: The structure of histargin, an inhibitor of carboxypeptidase B, produced by Streptomyces roseoviridis MF118-A5 strain, has been defined as N-[(S)-1-carboxy-4-guanidinobutyl]-N'-[(S)-1-carboxy-2-(imidazol-4 -yl) ethyl]ethylenediamine, by spectral analysis and chemical synthesis.
