Abstract
The invention relates to aminoacyl-tRNA synthetases that aminoacylate tRNA with 2-Aminoisobutyric acid (Aib), thus enabling the incorporation of the Aib into a growing polypeptide chain during translation, e.g. in eubacterial host cells such as E. coli. For example, but not limited to, the invention relates to new aminoacyl-tRNA synthetases and the uses hereof, as well as a method for producing polypeptides that contain one or more Aib.
Claims5
A 2-Aminoisobutyric acid-tRNA synthetase (AibRS) comprising an amino acid sequence of SEQ ID NO:
- 7 or a variant thereof and having the function of aminoacylating tRNA with 2-aminoisobutyric acid (Aib), wherein the variant of SEQ ID NO:
- 7 retains 215Gly and is at least 90% identical to SEQ ID NO:
- 7.
