Pyrrolysine (symbol Pyl or O^[2]) encoded by the 'amber' stop codon UAG, is a proteinogenic amino acid that is used in some methanogenic archaea and in bacteria.^[3]^[4] It consists of lysine with a 4-methylpyrroline-5-carboxylate in amide linkage with the ^εN of the lysine. Its pyrroline side-chain is similar to that of lysine in being basic and positively charged at neutral pH.^[5]^[6]
