    Abstract: Non-naturally occurring tRNASec and methods of using them for recombinant expression of proteins engineered to include one or more selenocysteine residues are disclosed. The non-naturally occurring tRNASec can be used for recombinant manufacture of selenocysteine containing polypeptides encoded by mRNA without the requirement of an SECIS element. In some embodiments, selenocysteine containing polypeptides are manufactured by co-expressing a non-naturally occurring tRNASec a recombinant expression system, such as E. coli, with SerRS, EF-Tu, SelA, or PSTK and SepSecS, and an mRNA with at least one codon that recognizes the anticodon of the non-naturally occurring tRNASec.

    Abstract: Nucleic acids encoding genes with SepRS and tRNASep activity for site specific incorporation of phosphoserine into a protein or polypeptide and methods of use thereof are described. Typically, SepRS preferentially aminoacylates tRNASep with O-phosphoserine and the tRNASep recognizes at least one codon such as a stop codon. In a preferred embodiment the nucleic acids are on vectors. In one embodiment, the vectors are expressed in cells such as bacterial cells, archeaebacterial cells, and eukaryotic cells. In an alternative embodiment, the vectors are expressed in an in vitro transcription/translation system. 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.

    Abstract: Nucleic acids encoding mutant elongation factor proteins (EF-Sep), phosphoseryl-tRNA synthetase (SepRS), and phosphoseryl-tRNA (tRNASep) and methods of use in site specific incorporation of phosphoserine into a protein or polypeptide are described. Typically, SepRS preferentially aminoacylates tRNASep with O-phosphoserine and the tRNASep recognizes at least one codon such as a stop codon. Due to the negative charge of the phosphoserine, Sept-tRNASep does not bind elongation factor Tu (EF-Tu). However, mutant EF-Sep proteins are disclosed that bind Sep-tRNASep and protect Sep-tRNASep from 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.
