  • Norine ID: NOR00215
  • Family: surfactin
  • Synonym(s): [Ala4]surfactin iC14;
  • Activity: surfactant, antibiotic
  • Class: lipopeptide
  • Formula: C50H87N7O13
  • Monoisotopic mass: 993.636185905 g/mol
  • Comment: The substitution of L-valine by L-alanine led to a decrease of the surfactant power of surfactin. The iC14 isoform represents 11% of total isoforms.
