| Abstract: | We isolated isodityrosine, a diphenyl ether linked amino acid, from cell wall hydrolysates and from two tryptic peptides of extensin. Determination of the molecular weights, net charges and composition of the peptides indicated that isodityrosine (IDT) can form a short intramolecular linkage in sequences consisting of:  | |
