A one-pot biotransformation for the generation of a series of L-aminotryptophans using a readily prepared protein extract containing tryptophan synthase is reported. The extract exhibits remarkable stability upon freeze-drying, and may be stored and used for long periods after its preparation without significant loss of activity.

This invention provides a method for producing proteins into which non-natural amino acids have been incorporated at desired positions involving the use of either prokaryote-derived or eukaryote-type aaRS* and prokaryotic cells or eukaryote-type as host cells, the method comprising steps of: (a) introducing genes encoding prokaryote-derived aminoacyl tRNA synthetase mutants having enhanced specificity to non-natural amino acids similar to given natural amino acids (compared with specificity to the natural amino acids) and tRNA genes for non-natural amino acids capable of binding to the non-natural amino acids in the presence of the prokaryote-derived aminoacyl tRNA synthetase mutants into prokaryotic cells that express genes encoding eukaryote-type aminoacyl tRNA synthetase having specificity to the given natural amino acids and tRNA genes capable of binding to the natural amino acids in the presence of eukaryote-type aminoacyl tRNA synthetase; and (b) knocking out genes encoding aminoacyl tRNA synthetase having specificity to the natural amino acids, which are inherent in the prokaryotic cells, and inherent tRNA genes capable of binding to the natural amino acids in the presence of the inherent aminoacyl tRNA synthetase.
The invention provides compositions and methods of identifying, modifying and producing modified target molecules, including therapeutic molecules by modification with non-natural amino acids. Certain aspects of the invention include methods of adding a chemical moiety to a target molecule, and the compositions resulting therefrom. Certain aspects of the invention also relate to kits for identifying, modifying and producing modified target molecules described herein.
