Preparations of syringomycin purified from three isolates of Pseudomonas syringae pv. syringae according to published procedures have been shown to contain a group of structurally related peptides which can be resolved by HPLC on a reverse phase column. In the acid hydrolysate of all components serine, phenylalanine, 2,4-diaminobutyric acid and arginine in the ratio 2:1:2:1 have been found. These products account for nearly 50% of the molecular weights determined by FAB mass spectrometry. Most of the antibiotic activity of the unfractionated preparations is recovered in a limited number of peaks.

Abstract
Preparations of syringomycin purified from three isolates of Pseudomonas syringae pv. syringae according to published procedures have been shown to contain a group of structurally related peptides which can be resolved by HPLC on a reverse phase column. In the acid hydrolysate of all components serine, phenylalanine, 2,4-diaminobutyric acid and arginine in the ratio 2:1:2:1 have been found. These products account for nearly 50% of the molecular weights determined by FAB mass spectrometry. Most of the antibiotic activity of the unfractionated preparations is recovered in a limited number of peaks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
