A series of adenosine triphosphate (ATP) derivatives bearing chloro, fluoro, amino, methyl, vinyl, and ethynyl groups at position 2 are synthesized and tested as substrates for RNA and DNA polymerases. The modified nucleotides work well in in vitro transcription with T7 RNA polymerase and primer extension (PEX) using engineered DNA polymerases (TGK, 2M) except for the bulkier 2-vinyl- and 2-ethynyl-ATP derivatives that give truncated products. However, in single nucleotide incorporation followed by PEX, they still can be used for site-specific incorporation of reactive modifications into RNA that can be further used for postsynthetic labeling through thiol-ene or Cu-catalyzed alkyne-azide cycloadditions reactions. All modified ATPs work in polyadenylation catalyzed by poly(A) polymerase to form long 3 '-polyA tails containing the modifications that also can be used for labeling.
