Abstact

Three for two: by using a Methanosarcina mazei PylRS triple mutant (Y306G, Y384F, I405R) the incorporation of two new exo-norbornene-containing pyrrolysine analogues was achieved. X-ray crystallographic analysis led to the identification of the crucial structural elements involved in substrate recognition by the evolved synthetase.
