Isolation and characterization of a new variant of surfactin, the [val7]surfactin

European Journal of Biochemistry 202 (1) 101-106

Abstract :

Reinvestigation of surfactin, a previously studied peptidolipid surfactant from Bacillus subtilis, by fast-atom-bombardment mass spectrometry and H-1-NMR spectroscopy, as well as by chemical methods, revealed the presence of a closely related second constituent. This new compound, [Val7]surfactin, differs from the known surfactin by the C-terminal amino acid residue which is valine instead of leucine.
