Some proteins in methanogenic archaea include '''[[Pyrrolysine|pyrrolysine (Pyl)]]'''. ''Methanosarcina barkeri'' monomethylamine methyltransferase (MtmB, [[1nth]], [[1l2q]]) was the first identified structure containing this amino acid, and in the crystal structure it is identified as BGX, with the rest of the amnio acid identified as LYS202<ref>PMID: 12029132</ref>. Chemically modified forms of pyrrolysine are present in the MtmB structures [[1tv2]], [[1tv3]], and [[1tv4]]<ref>PMID: 15380192</ref>. The [[PDB]] also contains several structures for pyrrolysyl-tRNA synthetase | Some proteins in methanogenic archaea include '''[[Pyrrolysine|pyrrolysine (Pyl)]]'''.
