Post-translational modificationi

This peptide occurs in both cyclic and linear forms. The linear form contains unmodified Trp-24, the cyclic peptide occurs in two forms with unmodified Trp-24, and with Trp-24 oxidized to form oxindolylalanine. Oxidation is enhanced by exposure to sunlight.1 Publication
