The molecule is a catecholate siderophore produced exclusively by Vibrio cholerae. It contains three molecules of 2,3-dihydroxybenzoate linked either directly or through L-threonine residues to the polyamine norspermidine. It has a role as a siderophore. It is a member of 1,3-oxazoles and a secondary carboxamide.
