Naturforsch. 53c, 295-304 (1998); received March 6 , 1998 Corrugatin, Lipopeptide, Siderophore, Pseudomonas corrugata From the culture medium of the phytopathogenic bacterium Pseudomonas corrugata, a lipopeptide siderophore was isolated that comprises interesting structural elements such as cyclic condensation products of the two amino groups of 2,4-diamino butyric acid with the carboxyl group of a second amino acid, and the rarely encountered L-threo-ß-hydroxy histi­ dine.
