Abstract
Nucleic acids encoding mutant elongation factor proteins (EF-Sep), phosphoseryl-tRNA synthetase (SepRS), and phosphoseryl-tRNA (tRNA) and methods of use in site specific incorporation of phosphoserine into a protein or polypeptide are described. Mutant EF-Sep proteins are disclosed that bind Sep-tRNAand protect Sep-tRNAfrom deacylation. In a preferred embodiment the nucleic acids are on vectors and are expressed in cells such as bacterial cells, archeaebacterial cells, and eukaryotic cells. Proteins or polypeptides containing phosphoserine produced by the methods described herein can be used for a variety of applications such as research, antibody production, protein array manufacture and development of cell-based screens for new drug discovery.
