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[edit]

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