Enduracididine is a non-proteinogenic α-amino acid that is a cyclic analogue of arginine.^[1] It is not genetically encoded into peptide sequences, but rather is generated as a posttranslational modification.

Biological roles

Enduracididine occurs rarely in nature, appearing principally in peptide antibiotics such as the antibacterial compounds enramycin and teixobactin.^[2]
