Abstract

Threose nucleic acid (TNA) is an artificial genetic polymer in which the natural ribose sugar found in RNA has been replaced with an unnatural threose sugar. TNA can be synthesized enzymatically using Therminator DNA polymerase to copy DNA templates into TNA. Here, we expand the substrate repertoire of Therminator DNA polymerase to include threofuranosyl adenine 3′-triphsophate (tATP). We chemically synthesized tATP by two different methods from the 2′-O-acetyl derivative. Enzyme-mediated polymerization reveals that tATP functions as an efficient substrate for Therminator DNA polymerase, indicating that tATP can replace the diaminopurine analogue (tDTP) in TNA transcription reactions.
