Abstract
The present invention relates to a variant of Terminal deoxynucleotidyl Transferase (TdT) which (i) comprises the amino acid sequence as set forth in SEQ ID Nº 2 or a functionally equivalent sequence, with at least an amino acid substitution at position corresponding to residue C302 or functionally equivalent residue, wherein the position is numbered by reference to the amino acid sequence set forth in SEQ ID Nº 1, (ii) is able to synthesize a nucleic acid fragment without template and (iii) is able to incorporate a modified nucleotide into the nucleic fragment.
Claims11
A variant of Terminal deoxynucleotidyl Transferase (TdT) which (i) comprises amino acids 130 to 510 of the amino acid sequence as set forth in SEQ ID NO:1, with an amino acid substitution selected from C302G/R/P/AN/S/N/O/D, wherein the position is numbered by reference to the amino acid sequence set forth in SEQ ID NO:1, (ii) is capable of synthesizing a nucleic acid fragment without template and (iii) is capable of incorporating a modified nucleotide into the nucleic acid fragment.
