  • Norine ID: NOR00480
  • DOI: 10.26097/nor00480
  • Family: kapakahine
  • Synonym(s): kapakahine A;
  • Activity: toxin
  • Class: peptide
  • Formula: C58H72N10O9
  • Monoisotopic mass: 1052.548373952 g/mol
  • Comment: Kapakahines share a unique structural feature: two tryptophan residues (Trp-1 and -2) are not linked by an amide bond but by a N-C bond from the indole nitrogen of Trp-1 to the indole carbon of Trp-2.Kapakahines C and D differ from A by the addition of the elements of H2O to the indole double bond of Trp-1 together with the formation of a bond between C-4 and N-1.
